Use cases like rotation require these hooks to have some context so they
know how to prepare and cleanup the frame buffer correctly.
For i915 specifically, object backing pages need to be mapped differently
for different rotation modes and the driver needs to know which mapping to
instantiate and which to tear down when transitioning between them.

In most situations it will be useful to have the old state passed to the
->atomic_update() callback. For example if a plane is being disabled the
new state's .crtc field will be NULL, but some drivers may rely on this
field to program the CRTCs registers.
v2: rename variable to old_plane_state and remove redundant comment as
suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to
drm-next and add a hunk for pending MSM mdp5 changes

Use drm_universal_plane_init() and drm_crtc_init_with_planes() rather
than the legacy drm_plane_init() / drm_crtc_init(). This will ensure
that the proper primary plane is registered with the DRM (and eventually
exposed to userspace in future patches).

Small typo I noticed in the mdp4_plane code.. no consequence because
PIPE_SRC_XY and PIPE_DST_XY have same register layout.

This can be shared between mdp4 and mdp5. Both use the same set of
parameters to describe the format to the hw.

There are some little bits and pieces that mdp4 and mdp5 can share, so
move things around so that we can have both in a common parent
directory.
