powerpc/book3e-64: Add helper function to setup IVORs
Not all 64-bit Book-3E parts will have fixed IVORs so add a function that cpusetup code can call to setup the base IVORs (0..15) to match the fixed offsets. We need to 'or' part of interrupt_base_book3e into the IVORs since on parts that have them the IVPR doesn't extend as far down.
