display: Set MONITOR_EDID_COMPLETE_RAWDATA for large EDIDs 

Quoting Adam Jackson:

"But the X driver looks like
it never sets MONITOR_EDID_COMPLETE_RAWDATA, which means the X core
doesn't know that any sections beyond the first are present, so it won't
ever hand back more than 128 bytes to clients.  Boo."

This patch is based on his.
