In future Book-E implementations IVORs will most likely go away and be replaced with fixed offsets. The IVPR will continue to exist to allow for relocation of the interrupt vectors. This code adds support to setup the IVORs as their fixed offset values per the ISA 2.06 spec when we transition from u-boot to another OS either via 'bootm' or a cpu release.
