Subject: [PATCH 160/217] cxl/list: Auto-enable 'single' mode for port listings

The --single parameter instructs the filter code to gate listing of
ancestor ports. However, that behavior can be inferred by attempts to list
a port without the --ports option, i.e. make:

    cxl list -p $port

...equivalent to:

    cxl list -P -S -p $port
