drm: Remove struct drm_driver.gem_prime_mmap

Browse Source 
All drivers initialize this field with drm_gem_prime_mmap(). Call
the function directly and remove the field. Simplifies the code and
resolves a long-standing TODO item.

struct drm_gem_object_funcs
---------------------------
GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way. Callbacks in drivers have been
converted, except for struct drm_driver.gem_prime_mmap.
