6.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

[ Upstream commit e1bc5c324bcca3acdbe817ccbf9aa7992d89479d ]

Add support to parse static master port map information from device tree.
This is required for correct port mapping between soundwire device and
master ports.
