Subject: [PATCH] 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.

I am not sure if this is the right place or value for this. It looks
like there is going to be another stub function added here, which is
going through -mm:

OK, that works/builds. It doesn't quite apply cleanly to linux-next-20200929
but that's a minor detail and easy to get around.

Thanks.
