drm/amd/display: Turn off internal backlight when plugging external monitor
[why]
For VG, we want to turn off power/backlight of the intenral panel when
plugging in external monitor and going to "external monitor only" mode.
[how]
For turning off power of the internal panel, ignore the config flag whic
bypasses power sequencing for eDP panels.
