[PATCH 4/8] drm/i915: Utilize intel_crtc_joined_pipe_mask() more

[Ville Syrjala]

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

Unify the master vs. slave handling in
intel_ddi_post_disable_hdmi_or_sst() by looping over all the
pipes in one go.

This also lets us move the intel_crtc_vblank_off() calls to
happen in a consistent place vs. the transcoder disable.
Previously we did the master vs. slaves on different sides
of that.
