Vishal,

Here is a series that adds a unit test for CXL bus operations around
port discovery and memory device enable/disable events. Along the way it
adds some helper commands ('cxl disable-bus') and calling convention
cleanups ('cxl list -p $port'). Some other miscellaneous fixups and
cleanups are thrown in for good measure.
