drm/xen: 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 xen. The only exception is gem_prime_mmap,
which is non-trivial to convert.
v2:
* convert xen_drm_drv_free_object_unlocked() to static
callback (Oleksandr)
