drm/i915: Introduce intel_crtc_joined_pipe_mask()

Browse Source 
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.

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