[Intel-gfx] [PATCH 3/4] drm/i915: Pimp DPLL ref/unref debugs

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

We currently have a debug message in intel_reference_shared_dpll()
but no counterpart in intel_unreference_shared_dpll(). Add one.

Switch to the [CRTC:...] notation for the pipe name while at it.
