From: Nicholas Kazlauskas <nicholas.kazlaus...@amd.com>
This reverts commit 4ac57a450da3.
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.
Fixes: 4ac57a450da3("drm/amd/display: Don't allow IPS2 in D0 for RCG Dynamic")
