drm/amd/display: Update SubVP Visual Confirm

[Why]
The visual confirm bar is displayed on all displays, but is only
updated on a flip. If an update causes SubVP to be disabled on
all displays, but there are no updates on the other displays, it
will lead to stale information displayed on the non-active
displays. An example of this is playing a fullscreen video on a
rotated display.

[How]
Add a procedure to update visual confirm color for all pipes when
committing a plane.
