[0/6] Bigjoiner refactoring

Message

There are few things we need to do for bigjoiner, in order
to improve code maintenance and also make testing for Bigjoiner
easier.
Those series contain addition of bigjoiner force debugfs option,
in order to be able to force bigjoiner even if there is no display
support, also we refactor pipe vs transcoder logic, as currently
it is a bit scattered between *_commit_modeset_enables/disables
and *_crtc_enable/disable functions. Same applies to encoders.
We made a decision to handle all the slaves in correspondent master
hook, so slaves and slave checks no longer would be in modesetting
level logic.

Stanislav Lisovskiy (5):
  Add a small helper to compute the set of pipes that the current crtc
    is using.
  drm/i915: Extract intel_ddi_post_disable_hdmi_or_sst()
  drm/i915: Utilize intel_crtc_joined_pipe_mask() more
  drm/i915: Handle joined pipes inside hsw_crtc_disable()
  drm/i915: Handle joined pipes inside hsw_crtc_enable()

Vidya Srinivas (1):
  drm/i915: Allow bigjoiner for MST
