Add support for system suspend into the CS35L41 HDA Driver.
Since S4 suspend may power off the system, it is required
that the driver ensure the part is safe to be shutdown before
system suspend, as well as ensuring that the firmware is
unloaded before shutdown. The part must then be restored
on system resume, including re-downloading the firmware.

The current code uses calls from the HDA Codec driver to
determine when to suspend/resume by calling hooks via the
hda_component binding.
However, this means the cs35l41 driver relies on the HDA
Codec driver to tell it when to suspend or resume,
creating an additional external dependency, and potentially
creating race conditions in the future. It is better for
the cs35l41 hda driver to decide for itself when the part
should be suspended or resumed.
This makes supporting system suspend easier.

Redesign the creation of ALSA controls so that the cs_dsp
pwr_lock is not held when calling snd_ctl_add(). Instead of
creating the ALSA control from the cs_dsp control_add callback,
do it after cs_dsp_power_up() has completed. The existing
functions are changed to return void instead of passing errors
back - this duplicates the original behaviour, as cs_dsp does
not abort firmware load if creation of a control fails.
It is safe to walk the control list without taking any mutex
provided that the caller is not trying to load a new firmware
or remove the driver in parallel. There is no other situation
that the list can change. So the caller can trigger creation
of ALSA controls after cs_dsp_power_up() has returned. A cs_dsp
control will have a non-NULL priv pointer if we have created
an ALSA control.
With the previous code the ALSA controls were created from
the cs_dsp control_add callback. But this is called with
pwr_lock held (as it is part of the DSP power-up sequence).
The kernel lock checking will show a mutex inversion between
this and the control creation path:
control_add
pwr_lock held, takes controls_rwsem (in snd_ctl_add)
get/put
controls_rwsem held, takes pwr_lock to call cs_dsp.
This is not completely theoretical. Although the time window
is very small, it is possible for these to run in parallel
and deadlock the old implementation.

The cs_dsp core will return an error if passed a NULL cs_dsp struct so
there is no need for the hda_cs_dsp_write|read_ctl functions to manually
check that. The cs_dsp core will also check the data is within bounds of
the control so the additional bounds check is redundant too. Simplify
things a bit by removing said code.

The HDMI driver skips the notification handling from the graphics
driver when the codec driver is being in the PM operation. This
behavior was introduced by the commit eb399d3c99 ("ALSA: hda - Skip
ELD notification during PM process"). This skip may cause a problem,
as we may miss the ELD update when the connection/disconnection
happens right at the runtime-PM operation of the audio codec.
Although this workaround was valid at that time, it's no longer true;
the fix was required just because the ELD update procedure needed to
wake up the audio codec, which had lead to a runtime-resume during a
runtime-suspend. Meanwhile, the ELD update procedure doesn't need a
codec wake up any longer since the commit 788d441a16 ("ALSA: hda -
Use component ops for i915 HDMI/DP audio jack handling"); i.e. there
is no much reason for skipping the notification.
Let's drop those checks for addressing the missing notification.

As the previous commit implies, a system may have a different SPI bus
number that is embedded in the device string. And, assuming the fixed
bus number is rather fragile; it may be assigned differently depending
on the configuration or on the boot environment. Once when a bus
number change happens, the binding fails, resulting in the silence.
This patch tries to make the matching a bit more relaxed, allowing to
bind with a different bus number (or without it). So the previous
fix, the introduction of ALC245_FIXUP_CS35L41_SPI1_2 fixup became
superfluous, and this is unified to ALC245_FIXUP_CS35L41_SPI_2.

Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM
device mapping is obsolete nowadays. The maximum number of the simultaneously
usable PCM devices is equal to the HDMI codec converters.
Remove the extra PCM devices (beyond the detected converters) and force
the use of the dynamic PCM device allocation. The legacy code is removed.
I believe that all HDMI codecs have the jack sensing feature. Move the check
to the codec probe function and print a warning, if a codec without this
feature is detected.

We fixed the potential deadlock at dynamic unbinding the HD-audio
codec at the commit 7206998f57 ("ALSA: hda: Fix potential deadlock
at codec unbinding"), but ironically, this caused another potential
deadlock. The current code uses refcount_dec() and waits for the
pending task with wait_event for dropping the refcount to 0. This
works fine when PCMs are assigned and actually waiting for the
refcount drop.
Meanwhile, when there was no PCM assigned, the refcount_dec() call
itself was supposed to drop to zero -- alas, it doesn't in reality;
refcount_dec() complains, spews kernel warning and it saturates
instead of dropping to 0, due to the nature of refcount_dec()
implementation. This eventually blocks the wait_event() wakeup and
the code get stuck there.
For avoiding the problem, we call refcount_dec_and_test() and skips
the sync-wait if it already reaches to zero.
The patch does a slight code reshuffling to make sure to invoke other
disconnect calls before the sync-wait, too.

When put_device() is called in another function it's hard to realize
that and easy to "fix" the code in a wrong way. Instead, move
put_device() to be in the same scope as get_device(), so we prevent
appearance of any attempts to "fix" the code.

The recent fix for IDT codecs to keep the power up while the beep is
enabled can be better integrated into the beep helper code.
This patch cleans up the code with refactoring.

The last fix for trying to recover the regression on AMD platforms,
unfortunately, leaded to yet another regression: it turned out that
IOMMUs don't like the usage of raw page allocations.
This is yet another attempt for addressing the log saga; at this time,
we re-use the existing buffer allocation mechanism with SG-pages
although we require only single pages. The SG buffer allocation
itself was confirmed to work for stream buffers, so it's relatively
easy to adapt for other places.
The only problem is: although the HD-audio code is accessing the
address directly via dmab->address field, SG-pages don't set up it.
For the ease of adaption, we now set up the dmab->addr field from the
address of the first page as default, so that it can run with the
HD-audio driver code as-is without the excessive call of
snd_sgbuf_get_addr() multiple times; that's the only change in the
memalloc helper side. The rest is nothing but a flip of the dma_type
field in the HD-audio side.

AZA HW may send a burst read/write request crossing 4K memory boundary.
The 4KB boundary is not guaranteed by Tegra HDA HW. Make SW change to
include the flag AZX_DCAPS_4K_BDLE_BOUNDARY to align BDLE to 4K
boundary.

Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length array
declaration in union audio_infoframe with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for a flexible-array member in a union.
