ASoC: cs42l42: Fix mono playback
I2S always has two LRCLK phases and both CH1 and CH2 of the RX must be enabled (corresponding to the low and high phases of LRCLK.) The selection of the valid data channels is done by setting the DAC CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel, CHB_SEL depends on the number of active channels. Previously for mono ASP CH2 was not enabled, the result was playing mono data would not produce any audio output.
