Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate
real CRC value of the last edid data block, and write it back.
Current edid CRC calculates routine adds the last CRC byte,
and check if non-zero.
This behavior is not accurate; actually, we need to return
the actual CRC value when

4.2.2.6
DP 1.4 edid corruption test requires source DUT to write calculated CRC, not
the corrupted CRC from reference sink.
Return the calculated CRC back, and initiate the required sequence.

DP 1.4 edid corruption test requires source DUT to write calculated
CRC, not the corrupted CRC from reference sink.
Return the calculated CRC back, and initiate the required sequence.
-v2: Have separate routine for returning real CRC
-v3: Rewrite checksum computation routine to avoid duplicated
