It was probably at one point for the sake of asm/openpromio.h but
that header has no dependencies on openprom.h

The only hit I can find in google code search, for non-kernel code, is
the SILO bootloader.

But that tree includes it's own copy of include/asm/openprom.h so
the actual kernel copy isn't even used.

I'd say we can stop exporting that header and also therefore not
worry about making phandle_t visible to userspace.
