Restructure how reset and poweroff are handled on PowerPC systems, since

the existing code was very platform specific, and broken for SMP systems
trying to reboot from KDB.

- Add a new PLATFORM_RESET() method to the platform KOBJ interface, and
  migrate existing reset functions into platform modules.
- Modify the OF_reboot() routine to submit the request by hand to avoid
  the IPIs involved in the regular openfirmware() routine. This fixes
  reboot from KDB on SMP machines.
- Move non-KDB reset and poweroff functions on the Powermac platform
  into the relevant power control drivers (cuda, pmu, smu), instead of
  using them through the Open Firmware backdoor.
- Rename platform_chrp to platform_powermac since it has become
  increasingly Powermac specific. When we gain support for IBM systems,
  we will grow a new platform_chrp.
