We're trying to introduce support for writeback connectors, a way to
expose in DRM the hardware functionality from display engines that
allows to write back into memory the result of the DE's composition
of supported planes.

Generic DRM support is available here [1] and will be merged once
this patchset gets approved for inclusion into igt. VC4 support
for writeback is added here [2] and for mali-dp is added here [3].

Changelog:
 - v2: Rebased on top of a844ccbdbab9fd16c37de81281c6281bc800e97a
 - v1: Original (re)submission [4]

Many thanks,
Liviu
