 * #FIXME:
 * TRANSCONF() uses pipe-based addressing via _MMIO_PIPE2().
 * Some GVT call sites pass enum transcoder instead of enum pipe.
 * Cast the argument to enum pipe for now since TRANSCODER_A..D map
 * 1:1 to PIPE_A..D.
 * TRANSCODER_EDP is an exception, the cast preserves the existing
 * behaviour but this needs to be handled later either by using the
 * correct pipe or by switching TRANSCONF() to use _MMIO_TRANS2().
