Change QEMU_FW_CFG_IO_BASE to shorter variant FW_CFG_IO_BASE and hand
over the actual port address in %r19 to SeaBIOS.

Devices on hppa occupy at least 4k starting at the HPA, so MEMORY_HPA+4k is
blocked (by Linux) for the memory module. I noticed this when testing the new
Linux kernel patch to let the fw_cfg entries show up in Linux under /proc.
The Linux kernel driver could not allocate the region for fw_cfg.
This new base address seems to not conflict.

The hppa_hardware.h file is shared with SeaBIOS. Sync it.

This adds emulation of Artist graphics good enough to get a text
console on both Linux and HP-UX. The X11 server from HP-UX also works.
Adjust boot-serial-test to disable graphics, so that SeaBIOS outputs
to the serial port, as expected by the test.

This patch fixes two issues in the hppa/parisc emulation:
1. The CPU HPA was wrong in the sense that we had negative module
offsets in the firmware-internal module table (which we ignored up to
now). Get it correct by changing the CPU HPA to 0xfffb0000 which is
greater than the DINO_HPA of 0xfff80000.
This change requires the seabios-firmware update.
2. Sven noticed that the FPU register cr10 is only able to reference up
to 8 FPUs, so let's reduce the maximum amount of SMP CPUs too.

Now that we have the prerequisites in target/hppa/,
implement the hardware for a PA7100LC.
This also enables build for hppa-softmmu.

[rth: Since it is all new code, squashed all branch development
withing hw/hppa/ to a single patch.]
