drm/amd/display: Revert "program k1/k2 divider for virtual signal for DCN32"
[Why & How]
This reverts commit e6cf22ef5fae493a99e162c3f2e7233448d2b970 since it
causes a SubVP related regression: "Switching between windowed video and
fullscreen can intermittently cause black screen"
Fixes: e6cf22ef5fae49 ("drm/amd/display: program k1/k2 divider for virtual signal for DCN32")
