This register is used to report the frequency (in Hz) of the clock source for
the global timers. Following reset, this register contains zero. The system
initialization code must initialize this register to one-eighth the MPIC
clock frequency. For the PHB implementation of the MPIC, a typical value
would be $7de290 (which is 66/8 MHz or 8.25 MHz).
