Brandon Bergren c583b02587 [PowerPC] PowerMac timebase sync for G4 
Summary:
Disable timebase on (some) AIM platforms (tested on PowerMac G4) prior
to synchronization.

Some platforms use a GPIO to enable and disable timebase, while others
use a platform function.

This mirrors 0d69f00b on mpc85xx.

Todo:
 * Implement various G5 timebase controls.
 * Print out platform code on unknown G5s so we can collect it.
 * Change API to be give/take pairs like Linux does so it's possible to
   do a software sync protocol.
