[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.
