A problem was found when EDID data sets for displays other
than the provided samples were generated. The patch series has
no effect on the provided samples that still match the data
used in drivers/gpu/drm/drm_edid_load.c.
The provided samples use small values for XOFFSET, XPULSE,
YOFFSET and YPULSE, where the error doesn't occur. This fix
corrects the use of that values in case of high values, because
the most significant bits were treated incorrectly.

The previous version made it necessary to first generate an
EDID data set without correct CRC and then to fix the CRC in
a second step. This patch series adds the CRC calculation to the
makefile in such a way that a correct EDID data set is generated
in a single build step.
