ASoC: codecs: wcd937x: Add static channel mapping support in wcd937x-sdw
Add static channel mapping between master and slave ports in wcd937x-sdw
driver.
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.
Implemented logic to read TX/RX channel mappings from device tree
properties (qcom,tx-channel-mapping and qcom,rx-channel-mapping).
Modified the wcd937x_connect_port to handle master channel masks during
port enable/disable operations.
Added wcd937x_get_channel_map api to retrieve the current master
channel map for TX and RX paths.
