drm/ttm: merge ttm_bo_api.h and ttm_bo_driver.h v2
Merge and cleanup the two headers into a single description of the object API. Also move all the documentation to the implementation and drop unnecessary includes from the header. No functional change. v2: minimal checkpatch.pl cleanup Signed-off-by: Christian König <[email protected]> Reviewed-by: Arunpravin Paneer Selvam <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
