Subject: drm/amd/display: Turn off internal backlight when plugging external
 monitor
Git-commit: 3ab55e3a1ebc22c1e0b7c72261a8c9fe78a3a09a
Patch-mainline: v6.0-rc1

[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.
