[PATCH 05/11] cxl/core: Introduce cxl_set_lock_class()

Update CONFIG_PROVE_CXL_LOCKING to use the common device-core helpers for device_lock validation. When CONFIG_PROVE_LOCKING is enabled and device_set_lock_class() is passed a non-zero lock class the core acquires the 'struct device' @lockdep_mutex everywhere it acquires the device_lock. Where
