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

Add a tracepoint for pipe crc. Makes life much simpler when staring at
traces when hunting for fifo underruns and other issues which cause
corrupted frames. We'll add the tracepoint before filtering out any
potentially bogus crcs during modeset (should actually verify if that
filtering is even correct anymore...)
