soundwire: mipi-disco: add new properties from 2.0 spec

The DisCo for SoundWire 2.0 spec adds support for new
'mipi-sdw-sdca-interrupt-register-list' and
'mipi-sdw-commit-register-supported'.

This patch only adds the definitions and property reads, but the use
of these properties will come at some point in the future when needed.

Note a slight conceptual disconnect between the MIPI DisCo definition
of a boolean property and the Linux implementation. The latter only
checks the presence of the property to set its value to 'true',
whereas the MIPI definitions allow for a property with a 'false'
value. This patch uses the new introduced mipi_device_property_read_bool()
to handle it.
