This patch fixes faulty behaviour in a setup where the input clock for the SRG is fed through the CLKR pin but the McBSP is configured to be master (SND_SOC_DAIFMT_CBS_CFS). In that case of course CLKR must not be configured as output pin. Otherwise the input clock is messed up horribly. The same reasoning applies if CLKX is configured as input for the SRG.
