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.

v2: Use the name 'pipe_crtc' for the per-pipe crtc pointer
