Subject: [PATCH v3 0/1] cxl/cli: enforce HPA-descending teardown order

This is v3 of the series. 
Apologies for the issues in v2 caused by an incorrect patch generation
step. v3 is generated from the correct tree after verifying, compiling
and testing, and it is confirmed to include correct changes.

The series implements:
 - Rework teardown ordering to account endpoint decoders shared across
   regions under the same bus/port
 - This addresses scenario described by Alison when a memdev is
   targeted by regions under multiple root decoders.
 - Correct formatting

Again, Alison, if you have a chance, please retest this version
against your configurations.
