[PATCH 07/20] drm/mediatek: Introduce GEM object functions



GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in mediatek. The only exception is gem_prime_mmap,
which is non-trivial to convert.
