Patch 2 is just for the crtc helpers, and matches what we've just done in
the i915 code. I think it fits in with the general design of the crtc
helpers.

Patch 1 matches a check in the intel code, too. So since applications
can't really know whether a flip to a different pixel format works I don't
think that capability is useful at all. And at least for i915 it's just
broken ;-) On patch 1 itself though: Just checking fb->pixel_format should
be good enough.
