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.
