drm/amd/display: Clear dpcd_sink_ext_caps if not set
[WHY]
Some eDP panels' ext caps don't set initial values
and the value of dpcd_addr (0x317) is random.
It means that sometimes the eDP can be OLED, miniLED and etc,
and cause incorrect backlight control interface.
[HOW]
Add remove_sink_ext_caps to remove sink ext caps (HDR, OLED and etc)
