From: Andrzej Turko <andrzej.turko@xxxxxxxxxxxxxxx>
Erase definitions from intel_memory_region.h and change the procedures
to operate on objects defined in i915_drm.h instead. Those objects
were defined in intel_memory_region.h in order to upstream memory region
stubs before the original definitions from i915_drm.h.
Modify tests using the memory region uapi in order to adapt them to the
changes in lib/i915/intel_memory_region.* files.
