I just realized that you're not using this actually. But I think we need
to use it to make *future* stuff work.

For the same reason PIPECONF() needs to use _PIPE2() macro, BCLRPAT needs
to use _TRANSCODER2() macro. Ie. the choice of which we use needs to be
based strictly on the offset range where the register lives. 
 0x6xxxx -> _TRANSCODER2()
 0x7xxxx -> _PIPE2()

PIPESRC() seems to be where it needs to be, ie. using _TRANCODER2().

So this also means we need the pipe_offsets[] array to have space for
PIPE_EDP_OFFSET.
