hdat/spira: Define ibm, primary-topology-index property per chip
HDAT provides Topology ID table and the primary topology location on
P10. This primary location points to primary topology entry in ID table
which contains the primary topology index and this index is used to
define the paste base address per chip.
This patch reads Topology ID table and the primary topology location
from hdata and retrieves the primary topology index in the ID table.
Make this primaty topology index value available with
ibm,primary-topology-index property per chip. VAS reads this property
to setup paste base address for each chip.
