In theory, the captured data will be combined from each cpu DAI if the dai link has more than one cpu DAIs. Therefore, the channel number should divide by num_cpus for each cpu/codec DAI. This commit introduces a flag to support the feature. Signed-off-by: Bard Liao <yung-chuan.liao@linux.intel.com>
Add SND_SOC_DAI_LINK_EVEN_CHANNEL flag on capture stream to split captured channels equally. Signed-off-by: Bard Liao <yung-chuan.liao@linux.intel.com>

In theory, the captured data will be combined from each cpu DAI if the
dai link has more than one cpu DAIs. Therefore, the channel number should
divide by num_cpus for each cpu/codec DAI.
This PR introduces a flag to support the feature and add the SND_SOC_DAI_LINK_EVEN_CHANNEL flag in sof_sdw.c
