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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
