Revert "drm/amd/display: Tune min clk values for MPO for RV"

This reverts commit 7d8657cf39613b08a3284975437dadf533e84aac.
Original issue of flash line when MPO enabled on idle screen
was fixed by raising clocks. This had negative effect of extra
power being drained. With the upstream commit d2d17cdb7adb
("drm/amd/display: disable dcn10 pipe split by default")
flash line issue was fixed and had positive effect for
battery life. Hence this patch is no more required.
