acpi_parse_cfmws() currently adds empty CFMWS ranges to numa_meminfo with the expectation that numa_cleanup_meminfo moves them to numa_reserved_meminfo. There is no need for that indirection when it is known in advance that these unpopulated ranges are meant for numa_reserved_meminfo in support of future hotplug / CXL provisioning. Introduce and use numa_add_reserved_memblk() to add the empty CFMWS ranges directly.
