drm: Clear fd/handle callbacks in struct drm_driver

Clear all assignments of struct drm_driver's fd/handle callbacks to
drm_gem_prime_fd_to_handle() and drm_gem_prime_handle_to_fd(). These
functions are called by default. Add a TODO item to convert vmwgfx
to the defaults as well.

v2:
	* remove TODO item (Zack)
	* also update amdgpu's amdgpu_partition_driver
