Several changes to resolve screen corruption sometimes seen with dpms
on ivy bridge, mostly based on upstream drm code:
- remove a workaround which was in itself causing issues
- switch the order of disabling fdi rx & tx
- disable DPLL_SEL when disabling the crtc
- add a few extra delays
Most of this concerns the gen5+ crtc disable function, and thanks
to a bunch of testers this is known to still work fine on gen 5/6/7.
