ACPI / NUMA: Add stub function for pxm_to_node()

After commit 01feba590cd6 ("ACPI: Do not create new NUMA domains from
ACPI static tables that are not SRAT"):

$ scripts/config --file arch/x86/configs/x86_64_defconfig -d NUMA -e ACPI_NFIT

$ make -skj"$(nproc)" distclean defconfig drivers/acpi/nfit/
drivers/acpi/nfit/core.c: In function ‘acpi_nfit_register_region’:
drivers/acpi/nfit/core.c:3010:27: error: implicit declaration of
function ‘pxm_to_node’; did you mean ‘xa_to_node’?
[-Werror=implicit-function-declaration]
 3010 |   ndr_desc->target_node = pxm_to_node(spa->proximity_domain);
      |                           ^~~~~~~~~~~
      |                           xa_to_node
cc1: some warnings being treated as errors
...

Add a stub function like acpi_map_pxm_to_node() had so that the build
continues to work.
