[PATCH v5 0/3] pull region-specific logic into new files

[Gregory Price]

cxl/core/region.c presently contains logic to handle cxl_region,
cxl_pmem_region, and cxl_dax_region.  The cxl_pmem_region and
cxl_dax_region management code deserves new files to make it clear
that this logic applies to a specific types of regions.

This also breaks up development space so fewer conflicts can occur, and
it becomes clear where changes are actually happening.

I snuck in a cleanup.h fixup for devm_cxl_add_dax_region to tidy up some
of the existing functions.

v4 -> v5:  Ira test fixes
           Jonathan nit fixes

v3 -> v4:  address DJ's feedback on cleanup.h patch:
           move __free() declaration to assignment point
           restore local dev variable

v2 -> v3:  renamed from x_region to region_x because it's prettier
           added cleanup.h
           small nits asked for by Jonathan (commas)

Gregory Price (3):
  cxl/core/region: move pmem region driver logic into region_pmem.c
  cxl/core/region: move dax region device logic into region_dax.c
  cxl/core: use cleanup.h for devm_cxl_add_dax_region
