Subject: [PATCH] powerpc/papr_scm: Move duplicate definitions to common header
files
The papr_scm uses PDSM structures like nd_papr_pdsm_health as the
PDSM payload which would be reused by ndtest. Since ndtest is arch
independent, move the PDSM header from arch/powerpc/include/uapi/
to the generic include/uapi/linux directory.
Also, there are some #defines common between papr_scm and ndtest
which are not exported to the user space. So, move them to a header
file which can be shared across ndtest and papr_scm via newly
introduced include/linux/papr_scm.h.
