Further testing showed some bugs in the 'jq' command use in cxl-test.
Fix those bugs and adjust test to work around false positive lockdep
splats.

CXL Dynamic Capacity Device (DCD) support is close to landing in the
upstream kernel.  cxl-cli requires modifications to interact with those
devices.  This includes creating and operating on DCD regions.
cxl-testing allows for quick regression testing as well as helping to
design the cxl-cli interfaces.

Add preliminary patches with some fixes.  Update libcxl, cxl-cli and
cxl-test with DCD support.
