Currently, the channel mask for each soundwire port is hardcoded in the wcd937x-sdw driver, and the same channel mask value is configured in the soundwire master. The Qualcomm boards like the QCM6490-IDP require different channel mask settings for the soundwire master and slave ports. With the introduction of the following channel mapping properties, it is now possible to configure the master channel mask directly from the device tree. The qcom,tx-channel-mapping property specifies the static channel mapping between the slave and master tx ports in the order of slave port channels which is adc1, adc2, adc3, adc4, dmic0, dmic1, mbhc, dmic2, dmic3, dmci4, dmic5, dmic6, dmic7. The qcom,rx-channel-mapping property specifies static channel mapping between the slave and master rx ports in the order of slave port channels which is hph_l, hph_r, clsh, comp_l, comp_r, lo, dsd_r, dsd_l.

Added a new field ch_mask to the qcom_swrm_port_config structure. This field is used to store the master channel mask, which allows more flexible to configure channel mask in runtime for specific active soundwire ports. Modified the qcom_swrm_port_enable function to configure master channel mask. If the ch_mask is set to SWR_INVALID_PARAM or is zero, the function will use the default channel mask.
