ASoC: simple-card-utils: Set sysclk on all components
[ Upstream commit ce2f7b8d4290c22e462e465d1da38a1c113ae66a ] If an mclk-fs value was provided in the device tree configuration, the calculated MCLK was fed into the downstream codec DAI and CPU DAI, however set_sysclk was not being called on the platform device. 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.
