Add suspend/resume state saving for OpenPIC on PowerMac. It's likely this
can be used on the others (cpcht and psim), but that has not been tested.

Add PIC support for IPIs. When registering an interrupt handler,
the PIC also informs the platform at which IRQ level it can start
assigning IPIs, since this can depend on the number of IRQs
supported for external interrupts.

Driver for OpenPIC compatible interrupt controllers.
It's fairly PowerMac specific at the moment, but that should be fixable.

Update to C99, s/__FUNCTION__/__func__/,
also don't use ANSI string concatenation.

Register definitions for the OpenPIC used in various models of
iMac/PowerMac/iBook/PowerBook.
