* Find out a few interesting information about the system (like CPU,

bus, and time base frequency) in the PPC boot loader, and propagate
  them to the kernel via kernel_args.
* Now we use the correct time base frequency for timer calculations.
* Implemented PPC specific system info stuff. Added a few PPC CPU
  types to <OS.h>.
