Seems to fix it on my Carrizo. I'm hesitant to propose this as a patch
because I don't know why it was skipped in the first place.

Doing a suspend during playback results in the uvd not resuming when
waking up with drm-next as the kernel.
Trying with cg_mask=pg_mask=0 It hangs on decode start. I've attached
the readout of the ring which looks normal.
Initially I thought maybe it's a PG related issue with suspend/resume
but since I can't reliably playback with PG/CG disabled I can't test
this theory.
