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...)
v2: s/crcs[5]/*crcs/ in the function argument because something
in the macros wants to do sizeof(crcs) and gcc likes to
warn us it's not an actual array so the size may not be
as expected. The silly bugger even does that for 'crcs[]'
causing us to lose any helpful syntactic hint that we
are in fact dealing with an array (kbuild test robot)
