Subject: [PATCH v6 2/3] soundwire: qcom: constify static struct qcom_swrm_data global variables

The qcom_swrm_data structures is only required for setting soundwire params,
so make the qcom_swrm_data structure const to allow the compiler
to put it in read-only memory and avoid unintentional modifications.
