As long as I can overwrite this flag in the board support I'm fine with
it. On our MC13783 based boards we have two external SSI channels (one
for record and one for playback). I merge them together to one six wire
SSI port using the AUDMUX since the imx-ssi driver currently can handle
only one SSI unit in FIQ mode.
