ASoC: SOF: Turn "firmware boot complete" message into a dbg message
Using a Canon Lake machine with the SOF driver causes dmesg to fill
up with a ton of these messages:

[  275.902194] sof-audio-pci 0000:00:1f.3: firmware boot complete
[  351.529358] sof-audio-pci 0000:00:1f.3: firmware boot complete
[  560.049047] sof-audio-pci 0000:00:1f.3: firmware boot complete
etc.

Since the DSP is powered down when not in used this happens everytime
e.g. a notification plays, polluting dmesg.

Turn this messages into a debug message, matching what the code already
does for the ""booting DSP firmware" message.

ASoC: SOF: Intel: remove unnecessary waitq before loading firmware
The HDA_DSP_IPC_PURGE_FW IPC from ROM is already handled in
cl_dsp_init(), and it will never be received in the IRQ thread,
so the wait condition on this IPC will never be satisfied. The
wait before loading firmware is redundant and can be removed safely.

ASoC: SOF: Introduce state machine for FW boot
Add a state machine for FW boot to track the
different stages of FW boot and replace the boot_complete
field with fw_state field in struct snd_sof_dev.
This will be used to determine the actions to be performed
during system suspend.

One of the main motivations for adding this change is the
fact that errors during the top-level SOF device probe cannot
be propagated and therefore suspending the SOF device normally
during system suspend could potentially run into errors.
For example, with the current flow, if the FW boot failed
for some reason and the system suspends, the SOF device
suspend could fail because the CTX_SAVE IPC would be attempted
even though the FW never really booted successfully causing it
to time out. Another scenario that the state machine fixes
is when the runtime suspend for the SOF device fails and
the DSP is powered down nevertheless, the CTX_SAVE IPC during
system suspend would timeout because the DSP is already
powered down.

ASoC: SOF: loader: fix snd_sof_fw_parse_ext_data
An error occurs during parsing more than one ext_data from the mailbox, because
of invalid data offset handling. Fix by removing the incorrect duplicate
increment of the offset.

The return value is also reset in the switch case. This does not change the
behavior but improves readability - there is no longer a need to check what the
return value of get_ext_windows is.

ASoC: SOF: loader: fix kernel oops on firmware boot failure
When we fail to boot the firmware, we encounter a kernel oops in
hda_dsp_get_registers(), which is called conditionally in
hda_dsp_dump() when the sdev_>boot_complete flag is set.

Setting this flag _after_ dumping the data fixes the issue and does
not change the programming flow.

ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creation
There is a lot of duplicate code when processing IPC firmware ready
notification and creating memory windows.

First step in reducing the code duplication is to introduce generic
functions:
	* sof_get_windows
	* sof_fw_ready
that will replace, in the first step, the specific implementation related
to baytrail related platforms:
	* byt_get_windows
	* byt_fw_ready

So we are basically moving code from intel/byt.c to loader.c keeping
in mind that mbox_offset is a per platform constant so we need to
use newly introduced snd_sof_dsp_get_mailbox_offset /
snd_sof_dsp_get_window_offset in order to get the correct
mbox offset / window offset value.

Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index
instead of the hardcoded BYT_DSP_BAR.

ASoC: SOF: Use struct_size() in kmemdup()
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace code of the following form:

sizeof(*w) + sizeof(struct sof_ipc_window_elem) * w->num_windows

with:

struct_size(w, window, w->num_windows)

Notice that variable size is unnecessary, hence it is removed.

This code was detected with the help of Coccinelle.

ASoC: SOF: fix race in FW boot timeout handling
A race condition exists in handling firmware boot timeout.
If FW sends FW_READY just after boot timeout has expired in
driver, a kernel exception will result as FW_READY handler
will be run while the state is still being cleaned up in
snd_sof_run_firmware(). Avoid the race by setting
boot_complete also in the error case.
