This debugfs interface will allow intel-gpu-tools test case
to verify if screen has been updated properly on cases like PSR.
v2: Accepted all Daniel's suggestions:
* grab modeset lock
* loop over connector and check DPMS on
* return errors
* use _eDP1 suffix for easy future extension
* don't cache crc_supported neither latest crc
* return crc as a full array and read it at once with aux.
* use 0 to turn TEST_SINK off.
* split the drm_helpers definitions in another patch.
v3: Accepted 2 Damien's suggestion: remove h from printf hexa
and return ENODEV when eDP not present instead of EAGAIN.
v4: Accepted 2 Jani' s suggestion: 1 path for unlock and remove
_retry from aux read.
v5: removing last missing useless _retry (by Damien)
