Enable devices on the 'cxl' bus to be attached to drivers. The initial user of this functionality is a driver for an 'nvdimm-bridge' device that anchors a libnvdimm hierarchy attached to CXL persistent memory resources. Other device types that will leverage this include: cxl_port: map and use component register functionality (HDM Decoders) cxl_nvdimm: translate CXL memory expander endpoints to libnvdimm 'nvdimm' objects cxl_region: translate CXL interleave sets to libnvdimm 'region' objects The pairing of devices to drivers is handled through the cxl_device_id() matching to cxl_driver.id values. A cxl_device_id() of '0' indicates no driver support. In addition to ->match(), ->probe(), and ->remove() support for the 'cxl' bus introduce MODULE_ALIAS_CXL() to autoload modules containing cxl-drivers. Drivers are added in follow-on changes.
