Revert "drm/amd/display: Don't allow IPS2 in D0 for RCG Dynamic"

This reverts commit 8488646966.

In some test environments causes reporting failures for S0i3/S4.

It shouldn't actually block entry provided there's no race with the
last state being updated, but currently suspecting there's an IPS2
check that's no longer being met.
