[Intel-gfx] [PATCH] drmmode_output_get_modes: Replace existing EDID property blob with new one

[Keith Packard]

This synchronizes the X EDID data with the kernel EDID data each time the
kernel data may have changed. Otherwise, X ends up stuck with the first EDID
data it sees, failing to accomodate to different monitors.
