Mario Limonciello 7c220f89ad Revert "drm/amd: Keep display off while going into S4"
commit 7e7cb7a13c upstream.

commit 68bfdc8dc0 ("drm/amd: Keep display off while going into S4")
attempted to keep displays off during the S4 sequence by not resuming
display IP.  This however leads to hangs because DRM clients such as the
console can try to access registers and cause a hang.
