[Intel-gfx] [PATCH v2 09/10] drm/i915: Disable LPT-H VGA dotclock during crtc disable

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Currently we leave the LPT-H VGA dotclock running after turning
the pipe/fdi/port/etc. Properly disable the VGA dotclock as
specified in the modeset sequence.

v2: Fix commit message typo (Paulo)
