Some CPU drivers (e. g. davinci-mcasp) may require the system clock to be configured as OUT, while there's no good way currently to set SND_SOC_CLK_OUT in simple-soc driver if the clock is fixed-rate. This patch makes asoc_simple_card_init_dai() initialize clock to SND_SOCK_CLK_OUT if explicitly stated in the relevant dts file. This change is transparent and doesn't change the default behavior.
