PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder.
Bigjoiner is making life even more confusing by introducing
a N:1 relationship between pipes and transcoders. In that case
we only enable/configure the transcoder corresponding to the
master pipe. Let's do some renames to make it clear we're dealing
with the transcoder rather than pipe when it comes to
PIPECONF/TRANSCONF.

I decided to leave the _cpu_ part out from the function/macro
names since the PCH transcoder related stuff already has a
_pch_ in their name. So shouldn't be possible to confuse them.
