crtc_state declaration can be moved into the loop.

I guess this part would be fine with using the drm stuff since it's a
high level thing, so kinda sits at the uapi level. But probably best
to convert to explicit .uapi anyway.

I'd prefer to get rid the the struct drm_crtc_state type variable
totally because if it remains I'm sure someone will use it.

Ugh, more aliasing variables. Can we just kill the drm_ one?

Otherwise looks good to me, so
