pci: Use a fixed numbering of PHBs on OPAL and improve log consistency
On P8, we calculate the OPAL ID of the PHB as a function of the physical
chip number and PHB index on that chip. P7 continues using "allocated"
numbers for now.
We also consistently print the PHB ID as a 4-digit hex number which
facilitates decoding it, and print the chip:index location in the probe
code to make it easier to correlate log entries.
