ChromeOS related codes. Here are the change details:

- Remove ChromeOS related kconfig switches, including
  SOC_INTEL_CSE_LITE_SKU which has dependency on ChromeOS flag
- Remove chromeos.c file
- Remove ChromeOS dsdt related codes from dsdt.asl & mainboard.c
- Remove ChromeOS GPIO related codes from variants.h & gpio.c
