Log Message:
Reorganise the IBM 4xx bus layout, using terminology from the IBM
documentation:
 - Remove "mainbus" altogether.
 - The new root is "plb" - the Processor Local Bus.
 - Attached to this is the "opb" - the On-chip Peripheral Bus, to which
   all the on-chip devices are attached (except the cpu and pci host
   bridge).
 - Port-specific code can pass an array of 'struct plb_dev' to
   config_rootfound() to attach extra devices to the plb.  The walnut
   port attaches a "pbus" (Peripheral Bus) in here for the RTC and
   pc keyboard controller to attach to.
There is still much 405GP specific code; the next round of changes will
generalise this to enable easier support for other 4xx CPUs.
