drm/amd/display: Only use ODM2:1 policy for high pixel rate displays
We only gain a benefit of using the ODM2:1 dynamic policy if it allow us
to decrease DISPCLK to use the VMIN freq. If the display config can
already achieve VMIN DISPCLK freq without ODM2:1, don't apply the
policy.
This patch was reverted but that causes some IGT regressions. To
unblock, the patch is being applied again until IGT failures are
fixed.
