mb/google/hatch (baseboard): add ACPI backlight support
Add ACPI backlight support for boards selecting BOARD_GOOGLE_BASEBOARD_HATCH. PUFF-based variants do not have an internal panel, so do not need this. Test: build/boot Windows 10 20H2 on google/akemi, verify display backlight controls functional.
