It's also set to drm_mode_card_res, and fb's min & max are not
necessarily the same as plane's min and max. But yes, I think you're
right, it's not related to crtc as such. With legacy the fb min defines
the crtc min (I think), but possibly with atomic that's not true.

It's a bit messed up, really. We should have separate limits for crtcs,
planes and fbs. For now the mode_config is all we have.
