dt-bindings: soundwire: Convert text bindings to DT Schema

Convert soundwire text bindings to DT Schema format.

Update interrupt property items as per device tree, as it is not
appropriately described in text file.
Update some of the properties description with minimum and maximum range.
Update secondary node info which is used to describe slave devices.
