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.
