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.

hw/hppa: Fix booting Linux kernel with initrd
Commit 20f7b890173b ("hw/hppa: Reset vCPUs calling resettable_reset()")
broke booting the Linux kernel with initrd which may have been provided
on the command line. The problem is, that the mentioned commit zeroes
out initial registers which were preset with addresses for the Linux
kernel and initrd.
Fix it by adding proper variables which are set shortly before starting
the firmware.

hw/hppa: Move software power button address back into PDC
The various operating systems (e.g. Linux, NetBSD) have issues
mapping the power button when it's stored in page zero.
NetBSD even crashes, because it fails to map that page and then
accesses unmapped memory.
Since we now have a consistent memory mapping of PDC in 32-bit
and 64-bit address space (the lower 32-bits of the address are in
sync) the power button can be moved back to PDC space.
This patch fixes the power button on Linux, NetBSD and HP-UX.

hw/hppa/machine: Disable default devices with --nodefaults option
Recognize the qemu --nodefaults option, which will disable the
following default devices on hppa:
- lsi53c895a SCSI controller,
- artist graphics card,
- LASI 82596 NIC,
- tulip PCI NIC,
- second serial PCI card,
- USB OHCI controller.
Adding this option is very useful to allow manual testing and
debugging of the other possible devices on the command line.
