cxl: Fix match_region_by_range() to use region_res_match_cxl_range()

match_region_by_range() is not using the helper function that also takes
extended linear cache size into account when comparing regions. This
causes a x2 region to show up as 2 partial incomplete regions rather
than a single CXL region with extended linear cache support. Replace
the open coded compare logic with the proper helper function for
comparison. User visible impact is that when 'cxl list' is issued,
no activa CXL region(s) are shown. There may be multiple idle regions
present. No actual active CXL region is present in the kernel.
