Move shared vram inline functions and structs into a header file
Signed-off-by: Arunpravin Arunpravin.PaneerSelvam@amd.com
Patches #1-#3 haven been pushed to drm-misc-next.
For this one it might be better to squash that into commit #5 as well since this is otherwise unused.
Might be a good idea to move the vram_mgr structur and function from amdgpu_ttm.h over to this file as well.
Regards, Christian.
