Add helper macros to iterate the current, or incoming set of planes attached to a crtc. These helpers are only available for drivers converted to use atomic-helpers. Signed-off-by: Rob Clark <robdclark@gmail.com> [danvet: Squash in fixup from Rob to move the planemask iterator to drm_crtc.h and document it. That one is needed by the atomic ioctl so can't be in a helper library.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
