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.
