spapr: nested: Introduce H_GUEST_[CREATE|DELETE] hcalls.
Introduce the nested PAPR hcalls:
- H_GUEST_CREATE which is used to create and allocate resources for
nested guest being created.
- H_GUEST_DELETE which is used to delete and deallocate resources
for the nested guest being deleted. It also supports deleting all nested
guests at once using a deleteAll flag.
