drm/todo: Fallout from v3d review 



Bunch of ideas from Eric and me on what we could do to make gem gpu
rendering drivers a notch simpler to type.

v2: Fix typo (Eric).

Contact: Maintainer of the driver you plan to convert



Clean up mmap forwarding

------------------------



A lot of drivers forward gem mmap calls to dma-buf mmap for imported buffers.

And also a lot of them forward dma-buf mmap to the gem mmap implementations.

Would be great to refactor this all into a set of small common helpers.

Put a reservation_object into drm_gem_object

--------------------------------------------



This would remove the need for the ->gem_prime_res_obj callback. It would also

allow us to implement generic helpers for waiting for a bo, allowing for quite a

bit of refactoring in the various wait ioctl implementations.
