mb/google/brya/var/*: Ensure LCD device has a valid address
Some variants added the generic gfx driver with an LCD device without specifying the address, which is required for the backlight controls to be functional under Windows. Add the address value where missing. Address value used (0x80010400) is same as on other Brya variants which did properly set it, and is taken from the ACPI 6.5 spec section B.4.2, _DOD (display output device enumeration), table B-2: - bit 31 = use the ACPI-defined (vs vendor-defined) bit scheme for bits 15-0 - bit 16 = platform firmware can detect the device - bit 10 = display type is internal/integrated flat panel (aka LCD) TEST=build/boot Win11 on google/brya (osiris), verify ACPI backlight controls functional.
