Some board designs hook the jack-detect up to an external GPIO,
rather then to one of the codec pins, add support for this.
Figuring out which GPIO to use is pretty much board specific so I've
chosen to let the machine driver pass the gpio_desc as data argument to
snd_soc_component_set_jack() rather then add support for getting the
GPIO to the codec driver. This keeps the codec code nice and clean.
Note that using an external GPIO for this conflicts with button-press
support, so this commit disables button-press support when an
external GPIO is used.

Some BYT platforms have a RT5651 codec while using an ACPI node with
a HID of 10EC5640 to describe the coded. Add the 10EC5640 HID to the
acpi_device_id list, so that the rt5651 will bind to the codec on these
devices.
Like the rt5645 and rt5670 drivers which also have the 10EC5640 ACPI HID
in their acpi_device_id list for similar reasons, the rt5651 driver checks
the codecs device-id register so that it will only bind if the codec
actually is a rt5651 and it will ignore actual rt5640 codecs.

Note this renames rt5651_set_jack, where all the jack-enable work was done
to rt5651_enable_jack_detect. This function can now no longer fail as it
does not request the IRQ anymore. It can still be passed an invalid jack

On removal we must free the IRQ *before* cancelling the jack-detect work,
so that the jack-detect work cannot be rescheduled by the IRQ.
Before this commit we were cancelling the jack-detect work from the
driver remove callback, while relying on devm to free the IRQ, which
happens after the remove callback.
This is the wrong order. This commit uses a devm-action to register
a devm callback which cancels the work, before requesting the IRQ
(devm tears things down in reverse order). This also allows us to
remove the now empty remove driver callback.

The idea behind exporting rt5651_apply_properties(), was for it to be used
on platforms where the platform code may need to add device-properties,
rather then relying only on properties set by the firmware. The platform
code could then call rt5651_apply_properties() after adding properties to
make sure that the codec driver was aware of the new properties.
But this is not necessary, as long as we do all property parsing from
the codec component-driver's probe function (or later) then the machine
driver can attach properties before calling snd_soc_register_card and
calling rt5651_apply_properties() for ordering reasons is not necessary.
This commit makes rt5651_apply_properties() private and adds 2 comments
documenting that all property parsing must be done from the codec
component-driver's probe function.

To determine if a plugged in jack is a headset (speakers + mic) or
headphones (mic contact shorted to ground) we use the micbias1 OVer Current
Detect (OVCD) functionality.
For this to work we need to have a micbias current to actually cause an
overcurrent condition when headphones are plugged in, so jack-type
detection requires both the LDO and micbias1 supplies to be on.
Before this commit there were 2 issues with the handling of this:
1) The LDO supply was force-enabled twice and never disabled again even
though it only needs to be forced on when doing jack-type detection
2) micbias1 was not force-enabled, and thus may be off when doing jack-type
detection
This commit fixes both by force-enabling the LDO and micbias1 supplies
before checking for an overcurrent condition and disabling them afterwards.
Note that both supplies will still get turned on normally (and OVCD will
protect against overcurrent) when the micbias1 is enabled normally because
the user has activated a sound stream recording from the mic.

is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback,
checking RT5651_GBL_CLK to determine if the sys-clk is PLL1 and thus the
PWR_PLL bit in reg PWR_ANLG2 must be set.
RT5651_GBL_CLK is changed by rt5651_set_dai_sysclk(), which gets called by
the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply.
This creates an ordering issue, during a dapm transition first all
connected() callbacks are called to build a list of supplies to enable
and then the complete list is walked to enable the supplies. Since the
connected() check happens before enabling any supplies,
is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set
based on the state the "Platform Clock" supply had *before* the transition.
This sometimes results in PWR_PLL being off, even though *after* the
transition PLL1 is configured as sys-clk.
This commit removes is_sys_clk_from_pll() instead simply setting / clearing
PWR_PLL in rt5651_set_dai_sysclk() based on the selected sys-clk, which
fixes this and as a bonus results in a nice cleanup.

Move all jack-detect initialization to rt5651_set_jack_detect. The main
reason to do this is so that platform code can setup jack-detect properties
after the device has been probed, which unfortunately is necessary on some
platforms.
This has 2 additional advantages:
1) Grouping all jack-detect init together makes it easier to follow what
is happening and results in a small reduction in the number of loc.
2) Before we would register the irq handler before rt5651->hp_jack was
assigned, leading to a potential NULL deref if the jack_detect work runs
before the machine driver has called set_jack.
