drm/radeon: Sync ME and PFP after CP semaphore waits v4
Fixes lockups due to CP read GPUVM faults when running piglit on Cape
Verde.
v2 (chk): apply the fix to R600+ as well, on CIK only the GFX CP has
a PFP, add more comments to R600 code, enable flushing again
v3: (agd5f): only apply to 7xx+. r6xx does not have the packet.
v4: (agd5f): split flush change into a separate patch, fix formatting
