drm/i915: Use generic vblank wait
However we already had vblank waits on the wrong side of
drm_vblank_{on,off}() calls due to various workarounds, so now we get
a warning more or less every time we do a modeset, and we fail to
wait for the vblank like we should.
Move the drm_vblank_{on,off}() calls back out from
intel_crtc_{enable,disable}_planes() so that all of these vblank waits
return to proper operation. Also move the cxsr wait a bit earlier so
that we can keep the encoder disable after we've turned off vblanks.
Moving stuff out from the plane enable/disable functions seems
preferrable to moving the workaround stuff in since the workarounds are
required only on specific platforms.
While at it switch over to the drm_crtc_ variants of the vblank on/off
functions.
