It has 3 value for each configuration, first one means the type: I2S(1) or PDM(2), second one is dataline mask for 'rx', third one is dataline mask for 'tx'. for example: fsl,dataline = <1 0xff 0xff 2 0xff 0x11>, it means I2S type rx mask is 0xff, tx mask is 0xff, PDM type rx mask is 0xff, tx mask is 0x11 (dataline 1 and 4 enabled).
