This uses the new sof-byt-codec-tdm4.m4 file, as the cht_bsw_nau8824 machine driver programs the link to TDM 4 slots 24 bit.
At first I thought it would be easier to just change the kernel to use the standard I2S 2 channel 24 bit format as other codecs do, but this causes problems with the right speaker/headphone channel unless the chan mixer-control for this is changed from CH1 to CH0, which requires UCM changes, so changing this at the kernel level will break setups with older UCM files (and updating UCM will break older kernels).
So we are stuck with the TDM 4 slots 24 bit format for these boards, as we cannot change it without causing regressions.
