mb/google/kahlee: Enable display backlight control in Windows 

Utilize the SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF to provide the Windows
driver with information on backlight settings.

TEST: Boot google/careena to Win10. Observe display brightness controls
functional after driver loads (immediately with patched driver,
30 minutes with unpatched).
