drm/udl: Remove udl implementation of GEM's free_object()
Udl's custom implementation for struct drm_gem_object_funcs.free_object
unmaps perma-mapped memory buffer before freeing the buffer object.
After switching to generic fbdev emulation and fixing the damage
handler, no perma-mapped buffers have to be released. Switch to SHMEM's
implementation of free_object.
