Only export the arizona_pm_ops if CONFIG_PM is set, but leave the
suspend/resume functions (and related code) outside #ifdef guards.
If CONFIG_PM is not set, the arizona_pm_ops will be defined as
"static __maybe_unused", and the structure plus all the callbacks will
be automatically dropped by the compiler.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

x86/ACPI boards with an arizona WM5102 codec ship with either Windows or
Android as factory installed OS.
The ACPI fwnode for the codec on Android boards misses 2 things compared
to the Windows boards (this is hardcoded in the Android board kernels):
1. There is no CLKE ACPI method to enabe the 32 KHz clock the codec needs
for jack-detection.
2. The GPIOs used by the codec are not listed in the fwnode for the codec.
The ACPI tables on x86/ACPI boards shipped with Android being incomplete
happens a lot. The special drivers/platform/x86/x86-android-tablets.c
module contains DMI based per model handling to compensate for this.
This module will enable the 32KHz clock through the pinctrl framework
to fix 1. and it will also register a gpio-lookup table for all GPIOs
needed by the codec + machine driver, including the GPIOs coming from
the codec itself.
Add an arizona_spi_acpi_android_probe() function which waits for the
x86-android-tablets to have set things up before continue with probing
the arizona WM5102 codec.

The ACPI fwnode describing the codec differs depending on the factory OS,

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

The Arizona driver has both some devices which only have an I2C
interface and some which only have a SPI interface. Currently both of
these share an of_match table, but this means inapproriate compatibles
are available for each interface. Tidy this up by creating a table for
each interface listing only the appropriate compatibles.

The Intel Bay Trail (x86/ACPI) based Lenovo Yoga Tablet 2 series use
a WM5102 codec connected over SPI.
Add support for ACPI enumeration to arizona-spi so that arizona-spi can
bind to the codec on these tablets.
This is loosely based on an earlier attempt (for Android-x86) at this by
Christian Hartmann, combined with insights in things like the speaker GPIO
from the android-x86 android port for the Lenovo Yoga Tablet 2 1051F/L [1].

Replace the custom arizona_of_get_type() function with the generic
device_get_match_data() helper. Besides being a nice cleanup this
also makes it easier to add support for binding to ACPI enumerated
devices.
While at it also fix a possible NULL pointer deref of the id
argument to the probe functions (this could happen on e.g. manual
driver binding through sysfs).

The (shared) probing code of the arizona-i2c and arizona-spi modules
takes the following steps during init:
1. Call mfd_add_devices() for a set of early child-devices, this
includes the arizona_ldo1 device which provides one of the
core-regulators.
2. Bulk enable the core-regulators.
3. Read the device id.
4. Call mfd_add_devices() for the other child-devices.
This sequence depends on 1. leading to not only the child-device
being created, but also the driver for the child-device binding
to it and registering its regulator.
This requires the arizona_ldo1 driver to be loaded before the
shared probing code runs. Add a softdep for this to both modules to
ensure that this requirement is met.
Note this mirrors the existing MODULE_SOFTDEP("pre: wm8994_regulator")
in the wm8994 code, which has a similar init sequence.
