cxl: Fix use of phys_to_target_node() for x86
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 enabled for both functions to work
correct. Update Kconfig to make sure the option is always enabled for
the driver.
