drm/amd/display: Skip backlight control delay on external powered links
[Why]
When an eDP panel is powered externally from a different GPU, we can avoid
waiting for hardware sequencing delays when switching the backlight on/off
as the display backlight is no longer powered by the original source.
[How]
This commit extends the 'link_powered_externally' variable to allow
bypassing hardware delays for additional backlight commands and force the
backlight on/off when a link is powered by another GPU.
