platform/x86: x86-android-tablets: Lenovo Yoga Tablet 2 830/1050 sound support

Browse source

The ACPI tables for the codec setup on the Lenovo Yoga Tablet 2 830/1050
miss 2 things compared to their Windows (Lenovo Yoga Tablet 2 1051)
counterparts:

1. There is no CLKE ACPI method to enable output of the 32KHz PMU clock on
   pin 6 of the SUS GPIO controller

2. The GPIOs used by the codec are not listed in the fwnode for the codec

Add pinctrl code to set the SUS6 pin mux manually and a gpio-lookup table
for the GPIOs to work around both issues.
