[ndctl PATCH 0/7] cxl/region: create-region command and unit

[Alison Schofield <alison.schofield@intel.com>]

While working to enhance the cxl-cli cxl-create-region command to handle
out-of-order target lists or no user-supplied target list, I ran into some
basic issues in the existing command that need to be addressed first.

Patches 1-2 consolidate and clean up the existing create-region tests.

Patches 3-6 fix target-list parsing and validation, release DPA after a
failed create, and move granularity validation ahead of region creation.
Each fix adds a test case for the problem it addresses.

Patch 7 corrects the documentation to reflect that --decoder is currently
required. Automatic root decoder selection will be considered separately
with the upcoming create-region usability work.

Developing tests for these fixes exposed two bugs and a topology gap in
the cxl_test mock module. A companion cxl_test series is here [1].
