[PATCH RESEND 01/15] ppc: spapr: Introduce Nested PAPR API related macros

[Harsh Prateek Bora <harshpb@linux.ibm.com>]

Adding new macros for the new hypercall op-codes, their return codes,
Guest State Buffer (GSB) element IDs and few registers which shall be
used in following patches to support Nested PAPR API.
