hw/hppa: Wire up Diva GSP card

Until now we used a standard serial-pci device to emulate a HP serial
console.  This worked nicely with 32-bit Linux and 32-bit HP-UX, but
64-bit HP-UX crashes with it and expects either a Diva GSP card, or a real
64-bit capable PCI graphic card (which we don't have yet).
In order to continue with 64-bit HP-UX, switch over to the recently
added Diva GSP card emulation.
