Change the PS3 irq allocation routines to take an argument indicating which
cpu (processor thread) the interrupt should be serviced on.
The current system configuration favors device interrupts that are serviced
on cpu0, so that is used as the default.

Fix two minor bugs in the PS3 system bus mmio region code. First, on error or
when freeing a region, retain the bus_addr and len fields to allow subsequent
calls to create the region. Second, correct the region address argument to the
lv1_unmap_device_mmio_region() call.
Fixes modprobe/rmmod of some drivers.

Some motherboards are broken and have no address set. Failing at probe time
prevents the device from ever being used (like to download a fixed BIOS). Instead
warn on probe and check again when device is brought up. That way the address
