Copy the damaged areas which are still valid in the other scanout pixmap
from there, then only copy the remaining damaged area from the screen
pixmap.
This is slightly more efficient (only needs one Damage record instead of
two, and only needs to copy each screen update across PCIe once with
ShadowPrimary and a discrete GPU), and will be significantly more
efficient for PRIME with the following change.

Only copy once for each time we update the corresponding scanout pixmap.
This can significantly reduce the bandwidth usage when there are
frequent updates to the screen pixmap.
This initial implementation only works when both the master and slave
screens use this driver.

We failed to do this when going back to scanning out directly from the

As a bonus, since we now destroy drmmode_crtc->scanout[] after setting
