  Revamp the interrupt handling in support of INTR_FILTER. This includes:
  o  Revamp the PIC I/F to only abstract the PIC hardware. The
     resource handling has been moved to nexus, where it belongs.
  o  Include EOI and MASK+EOI methods to the PIC I/F in support of
  o  With the allocation of interrupt resources and setup of
     interrupt handlers in the common platform code we can delay
     talking to the PIC hardware after enumeration of all devices.
     Introduce a call to powerpc_intr_enable() in configure_final()
     to achieve that and have powerpc_setup_intr() only program the
     PIC when !cold.
  o  As a consequence of the above, remove all early_attach() glue
     from the OpenPIC and Heathrow PIC drivers and have them
     register themselves when they're found during enumeration.
  o  Decouple the interrupt vector from the interrupt request line.
     Allocate vectors increasingly so that they can be used for
     the intrcnt index as well. Extend the Heathrow PIC driver to
     translate between IRQ and vector. The OpenPIC driver already
     has the support for vectors in hardware.
