This patch seems to do this unconditionally.  This is fine for
configurations where the SoC is the only thing driving the bus but will
mean that for TDM configurations where something else also drives some
of the slots we'll end up with both devices driving simultaneously.  The
safest thing would be to set this only if TDM isn't configured.
