phys/P10: Use topology index to get phys mapping
This fixes multipchip rainier boot issue.
for Rainer:
chip0: ibm,primary-topology-index = < 0x0>;
chip1: ibm,primary-topology-index = < 0x4>;
chip2: ibm,primary-topology-index = < 0x8>;
chip3: ibm,primary-topology-index = < 0xc>;
for Denali:
node0:
chip0: ibm,primary-topology-index = < 0x0>;
chip1: ibm,primary-topology-index = < 0x1>;
chip2: ibm,primary-topology-index = < 0x2>;
chip3: ibm,primary-topology-index = < 0x3>;
node1:
chip0: ibm,primary-topology-index = < 0x4>;
chip1: ibm,primary-topology-index = < 0x5>;
chip2: ibm,primary-topology-index = < 0x6>;
chip3: ibm,primary-topology-index = < 0x7>;
Note that bmc_create_node() gets called very early in the boot process.
Hence we have to traverse through HDAT ntuple to get right topology index.
May be we can optimize pcid_to_topology_idx() function as its pretty
much duplicate of pcid_to_chip_id(). But for now lets keep it as
separate function.
