I mean, I took a while to sort functions in my head. However, finally, I got it, and the change looks good.

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