drm/amd/display: Optimize link power-down when link powered externally
[Why]
When an eDP panel is powered externally by a different GPU, we don't need
to wait for hardware sequencing delays when powering down a link, as the
display is not dependent on the GPU being powered down.
[How]
This commit adds a variable 'link_powered_externally' to indicate when a
link is being powered by another GPU.
