Robert Mader adc776d0d7 crtc/kms: Pass on src and dst rects to primary plane assignments
This allows us to pass on the related data from CoglScanouts.

If dst_rect does not match the mode, we assume that not covered areas
are opaque black - usually black bars around a centered surface.

While such driver behaviour does not appear to be documented (well) yet,
it seems to be followed by all known existing drivers and is used in a
similar way in ChromeOS.
