drm/vram: Don't export driver callback functions for PRIME

Browse source 
PRIME functionality is now provided by GEM object functions. The driver
callback functions are obsolete. So this patch renames them and turns
them into static internal functions of the VRAM helper library. The
implementation of gem_prime_mmap is now unused and the patch removes it.

v3:
	* kept each renamed function at its original location within file
	* kept documentation

GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.
DRM_GEM_CMA_VMAP_DRIVER_OPS, DRM_GEM_SHMEM_DRIVER_OPS already support this, but
DRM_GEM_VRAM_DRIVER_PRIME does not yet and needs to be aligned with the previous
two. We also need a 2nd version of the CMA define that doesn't require the
We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.
