Support sysctl machdep.cpu_speed for 7447A and 7448 based Macs. On those
machines the CPU's DFS (Dynamic Frequency Switching) feature is used instead
of a GPIO to control the speed.
Two new functions in powerpc/oea/cpu_subr.c were introduced to support
reading and writing of DFS: cpu_get_dfs() and cpu_set_dfs(). Also works
for multiple CPUs, but not before interrupts are enabled.
