Wow, so many drivers get nuked!

All drivers initialize this field with drm_gem_prime_mmap(). Call
the function directly and remove the field. Simplifies the code and
resolves a long-standing TODO item.

I have tested this patch briefly with drm/amdgpu(RX560), Running glmark2, the rendered scene looks OK.

But single driver is self-sharing.  I think I should test this more with multiple video card.

No need to test; it's equivalent to removing a wrapper.

But new DRM (un-upstreamed) drivers cannot be compiled anymore with this patch applied.

This makes them all out-of-date or going to be outdated; this is embarrassing!
