Jason Thorpe 5ec4f1d348 hw/alpha: Provide a PCI-ISA bridge device node
- Move initialization of the ISA bus from typhoon_init() to clipper_init();
  this apsect of device topology is really associated with the individual
  model, not the core logic chipset.  typhoon_init() now returns the IRQ
  to use for the output of the ISA PIC.

- In clipper_init(), instantiate an i82378 instance, and connect its
  PIC output to the ISA IRQ input provided by typhoon_init().  Remove
  the explicit instantiations of i8254 and i82374, as these devices
  are subsumed by the i82378.
