drm/mipi-dbi: Support shadow-plane state
Implement MIPI DBI planes with struct drm_shadow_plane_state, so that the
respective drivers can use the vmap'ed GEM-buffer memory. Implement state
helpers, the {begin,end}_fb_access helpers and wire up everything.
With this commit, MIPI DBI drivers can access the GEM object's memory
that is provided by shadow-plane state. The actual changes to drivers
are implemented separately.
v2:
* use shadow-plane state directly (Noralf)
