[ndctl,00/15] cxl-cli test and usability updates

Message

The v6.1-rc4 kernel picks up new cxl_test infrastructure for a switch
attached to a single-port host-bridge. While extending the region
creation and topology tests for that change, some additional updates
were identified. The main one is the ability to elide the "ways"
"memdevs" arguments to 'cxl create-region'. Those parameters are now
derived by the result of a topology walk under the given root decoder.
I.e.:

    cxl create-region -d decoder3.4

...will internally perform a:

    cxl list -M -d decoder3.4

...operation and use those memdevs as region targets.

This also updates 'create-region' size detection to be maximum free
extent in the decoder, or the available capacity in the target memdevs,
whichever is smaller.

Some miscellaneous fixes and updates are included as well.
