[POWERPC] ps3: system bus minor mmio fix
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.
