Subject: mb/google/hatch (baseboard): add ACPI backlight support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
