Changes in v3:
- Rebase onto 7.4-rc1

Changes in v2:
- Patch 2: Avoid duplicate look up of auto region window (RichardC)
- CoverLetter: Add link to the ndctl companion series

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.
Developing tests for those fixes exposed two bugs and a topology gap in
the cxl_test mock module.

This cxl_test series addresses those issues:
1/3 fixes a DPA skip leak across mock decoder reset.
2/3 skips auto-region setup when no volatile window is active.
3/3 adds two x1 CFMWS windows needed to exercise root decoder selection.

A companion ndctl series[1] fixes the existing cxl-create-region issues
in cxl-cli, clearing the way for out-of-order or automatically generated
target lists.

These changes preserve the existing cxl_test unit test behavior while
enabling new create-region test cases.
