Merge airlied/drm-next into drm-intel-next-queued
Commit 'aee3bac0a3a8 ("drm/i915/psr: Tie PSR2 support to Y
coordinate requirement")' got merged to drm-intel-next-queued
but the variable was defined commit 'c5fe47327b06 ("drm: Add PSR
version 3 macro") who was merged through drm-misc.
So backmerging to get drm-intel-next-queued compiling back again.
