The primary role of @dev is to host the mappings for devm operations. @dev is too ambiguous as a name. I.e. when does @dev refer to the 'struct device *' instance that the registers belong, and when does @dev refer to the 'struct device *' instance hosting the mapping for devm operations? Clarify the role of @dev in cxl_register_map by renaming it to @host. Also, rename local variables to 'host' where map->host is used.
