drm/ttm: rename ttm_fbdev_mmap
Rename ttm_fbdev_mmap to ttm_bo_mmap_obj. Move the vm_pgoff sanity
check to amdgpu_bo_fbdev_mmap (only ttm_fbdev_mmap user in tree).
The ttm_bo_mmap_obj function can now be used to map any buffer object.
This allows to implement &drm_gem_object_funcs.mmap in gem ttm helpers.
v3: patch added to series
