intel_pin_and_fence_fb_obj() only needs the framebuffer, and the desird
rotation (to find the right GTT view for it), so no need to pass all
kinds of plane stuff.

Feels indeed a bit like a bikeshed and just churn without resolving the
"pass vma in plane_state around" idea for real. But meh, it's imo not
worse than the existing code, and looks correct. Less churn would make me
a happier reviewer thought (there's a pile of whitespace in here too).

It is worse, and is definitely not better. :(

I might accept that if it wasn't for the ugly 'if (!plane_state)' mess.

Ok you have a point there. Maybe there should be a fake default state available, if somehow possible? Would all zero be a valid state?
