Some platform devices such as the Xilinx Audio Formatter need to know the MCLK as well. Call snd_soc_component_set_sysclk on each component in the stream to set the proper sysclk value in addition to the existing call of snd_soc_dai_set_sysclk on the codec DAI and CPU DAI. This may end up resulting in redundant calls if one of the snd_soc_dai_set_sysclk calls ends up calling snd_soc_component_set_sysclk itself, but that isn't expected to cause any significant harm.
