Subject: [PATCH 012/217] Expose ndctl_bus_nfit_translate_spa as a public
function.
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.
