Pull CXL updates from Dave Jiang:
 "The most significant changes in this pull request is the series that
  introduces ACQUIRE() and ACQUIRE_ERR() macros to replace conditional
  locking and ease the pain points of scoped_cond_guard().

  The series also includes follow on changes that refactor the CXL
  sub-system to utilize the new macros.

  Detail summary:

   - Add documentation template for CXL conventions to document CXL
     platform quirks

   - Replace mutex_lock_io() with mutex_lock() for mailbox

   - Add location limit for fake CFMWS range for cxl_test, ARM platform
     enabling

   - CXL documentation typo and clarity fixes

   - Use correct format specifier for function cxl_set_ecs_threshold()

   - Make cxl_bus_type constant

   - Introduce new helper cxl_resource_contains_addr() to check address
     availability

   - Fix wrong DPA checking for PPR operation

   - Remove core/acpi.c and CXL core dependency on ACPI

   - Introduce ACQUIRE() and ACQUIRE_ERR() for conditional locks

   - Add CXL updates utilizing ACQUIRE() macro to remove gotos and
     improve readability

   - Add return for the dummy version of cxl_decoder_detach() without
     CONFIG_CXL_REGION

   - CXL events updates for spec r3.2

   - Fix return of __cxl_decoder_detach() error path

   - CXL debugfs documentation fix"
