drm/dp: add helpers for capture of frame CRCs
Adds helpers for starting and stopping capture of frame CRCs through the
DPCD. When capture is on, a worker waits for vblanks and retrieves the
frame CRC to put it in the queue on the CRTC that is using the
eDP connector, so it's passed to userspace.
v2: Reuse drm_crtc_wait_one_vblank
Update locking, as drm_crtc_add_crc_entry now takes the lock
v3: Don't call wake_up_interruptible directly, that's now done in
drm_crtc_add_crc_entry.
v4: Style fixes (Sean Paul)
Reworked retry of CRC reads (Sean Paul)
Flush worker after stopping CRC generationa (Sean Paul)
v5: Move back to make the retry explicitly once
v6: Set and use the drm_crtc backpointer (Sean Paul)
