[POWERPC] PS3: System manager support

Browse Source 
Add PS3 system manager support and the ppc_md routines restart() and
power_off().

The system manager provides an event notification mechanism for reporting
events like thermal alert and button presses.  It also provides support to
control system shutdown and startup.
