When the number of channels for an I2S interface is overridden from userspace, if the I2S interface is being used in TDM mode where there are more than 2 channels, the I2S SLOT_CTRL register may not be configured correctly. For example, if using the AMX to the multiplex 4 mono channels into a single 4 channel TDM stream that is then routed to an I2S interface, the number of channels seen by the I2S interface is 4 where as each input stream to the AMX only has a single channel. Therefore, the number of channels for the I2S interface needs to be manually set to 4 from userspace. However, when this is done the I2S SLOT_CTRL register is still configured with the default RX and TX slot mask. To fix this, if the number of channels for the I2S interface is overridden from userspace, then if using TDM modes, also override the RX and TX slot mask.
