It doesn't seem like these two types of flags should be mixed because
they overlap. DISPLAY_FLAGS_PIXDATA_POSEDGE has the same value as the
DRM_MODE_FLAG_CSYNC define.

The definition of the DISPLAY_FLAGS_PIXDATA_POSEDGE is also not very
clear to me. I don't think we have an equivalent DRM_MODE_FLAG_* but
we could add one if there's really a need.
