The motivation is to allow access to ACPI defined NVDIMM Root Device
_DSM Function Index 5(Translate SPA). The rest of the _DSM functions,
which are mostly ARS related, are already public.
Basically move ndctl_bus_nfit_translate_spa declaration from private.h
to libndctl.h.
Changes from V1:
- Group function declaration in libndctl.h with other ndctl_bus_* functions.

Hi Erwin,
I forgot to mention this for v1 but you're also missing your own Signed-
off-by. If you commit using 'git commit -s', that should automatically
add it for you.
Do you mind sending a v3 with that, and I'll get it queued up.
There's also a malformed email CC - I think you want to quote the --cc
line to git-send-email like: --cc="name <email>"
