[PATCH 18/36] drm/amd/display: fix stuck test pattern on right half of display

[Bhawanpreet Lakha]

From: Zi Yu Liao <ziyu.liao at amd.com>

[why]
With visual confirm enabled, displays where ODM combine is enabled
has a test pattern stuck on the right half of the display even
though the display is unblanked.

[how]
Add a condition to not show the colour ramp test pattern when the
display is unblanked.
