mfd: arizona-spi: Add Android board ACPI table handling

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.
