* The PMC-Sierra SLP interrupts are arranged in a 3 level cascaded

* and are assigned the interrupt range 0-7. The second level is the SLM
* interrupt controller and is assigned the range 8-39. The third level
* comprises the Peripherial block, the PCI block, the PCI MSI block and
* the SLP. The PCI interrupts and the SLP errors are handled by the
* relevant subsystems so the core interrupt code needs only concern
* itself with the Peripheral block. These are assigned interrupts in
