[ Upstream commit 3d71a8726e ]
[WHY]
Some eDP panels's ext caps don't write initial value cause the value of
dpcd_addr(0x317) is random. It means that sometimes the eDP will
clarify it is OLED, miniLED...etc cause the backlight control interface
is incorrect.
[HOW]
Add a new panel patch to remove sink ext caps(HDR,OLED...etc)
