[PATCH 19/22] drm/amd/display: Fix pixel rate divider policy for 1 pixel per cycle config

[Zaeem Mohamed]

From: Meenakshikumar Somasundaram <meenakshikumar.somasundaram at amd.com>

[Why]
Pixel rate dividor was not programmed correctly for 1 pixel per cycle
configuration for empty tu case.

[How]
Included check for empty tu when pixel rate dividor values were selected.
