  hw/alpha: Set minimum PCI device ID to 1 to match Clipper IRQ mappings

Since we are emulating a Clipper device topology, we need to set the
minimum PCI device ID to 1, as there is no IRQ mapping for a device
at ID 0 (see sys_dp264.c:clipper_map_irq()).

- Add a 'devfn_min' argument to typhoon_init().  Pass that argument
  along to pci_register_root_bus().
- In clipper_init(), pass PCI_DEVFN(1, 0) as the minimum PCI device
  ID/function.

  hw/alpha: Provide console information to the PALcode at start-up

Redefine the a2 register passed by Qemu at start-up to also include
some configuration flags, in addition to the CPU count, and define
a flag to mirror the "-nographic" option.

  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.
