drm: Pass in new and old plane state to prepare_fb and cleanup_fb
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. v2: Made passed in states const.
