drm_hwcomposer: Implement *DisplayBrightness* stubs
Implement *DisplayBrightness* stub to be able boot
Android 11 using android.hardware.graphics.composer@2.3-service.
This change caused by error during boot:
failed to get hwcomposer2 function 61
61 is equal to SetDisplayBrightness.
GetDisplayBrightnessSupport is a companion of it.
