[PULL 34/38] spapr: nested: Initialize the GSB elements lookup table. |

From: Harsh Prateek Bora <harshpb@linux.ibm.com>
Nested PAPR API provides a standard Guest State Buffer (GSB) format
with unique IDs for each guest state element for which get/set state is
supported by the API. Some of the elements are read-only and/or guest-wide.
Introducing additional required GSB elements and helper routines for state
exchange of each of the nested guest state elements for which get/set state
should be supported by the API.
