[PATCH] cxl: Fix use of phys_to_target_node() outside of init section

[Robert Richter]

The CXL driver uses both functions phys_to_target_node() and
memory_add_physaddr_to_nid(). The x86 architecture relies on the
NUMA_KEEP_MEMINFO kernel option to be set. Enable the option for the
driver accordingly.
