[PATCH 2/8] drm/i915: Introduce intel_crtc_joined_pipe_mask()

[Ville Syrjala]

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

Add a small helper to compute the set of pipes that the current
crtc is using.

And we have at least one trivial place in
intel_ddi_update_active_dpll() where we can use it
immediately, so let's do that.
