The adjustead_mode crtc_ timings are what we will program into the hardware,
so it's those timings we should be looking practically everywhere.

The normal and crtc_ timings should differ only when stere doubling is
used. In that case the normal timings are the orignal non-doubled
timigns, and crtc_ timings are the doubled timings used by the hardware.

The only case where we continue to look at the normal timings is when we
pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC.
drm_edid keeps the modes aronund in the non-double form only, so it
needs the non-double timings to match against.

Done with sed
's/adjusted_mode->\([vhVH]\)/adjusted_mode->crtc_\1/g'
's/adjusted_mode->clock/adjusted_mode->crtc_clock/g'
with a manual s/VDisplay/vdisplay/ within the comment in intel_dvo.c

According to the PCI docs and Rafael, we don't need to be doing explicit
enables and disables in our init and teardown routines, as they're taken
care of by the PCI core.  So drop the pm_runtime_disable() at teardown
and pm_runtime_set_active() at init.
