  Log Message:
  -----------
  New SeaBIOS-hppa version 6

Staring with SEABIOS_HPPA_VERSION 6 the serial ports are now emulated as
on physical hardware, with LASI UART being serial port #0 and DINO UART
as serial port #1. On older versions those ports were swapped.

This SeaBIOS-hppa fix is needed to allow fixing the qemu serial
pass-through from host to guest.

  hppa: Sync contents of hppa_hardware.h header file with SeaBIOS-hppa

The hppa_hardware.h header file holds many constants for addresses and
offsets which are needed while building the firmware (SeaBIOS-hppa) and
while setting up the virtual machine in QEMU.

That's why this header file needs to be in sync between both source code
repositories. This patch adds a comment mentioning this dependency at
the top of this file and restores some DINO relevant offsets.

  hppa: Fix serial port assignments and pass-through

This fixes the serial ports in the emulation to behave as on original
hardware.

On the real hardware, the LASI UART is serial port #0 and the DINO UART
is serial port #1. This is fixed in SeaBIOS-hppa firmware v6, which is
why at least this firmware version is required.

The serial port addresses in hppa/hppa_hardware.h have to be swapped,
and when creating the virtual serial ports the correct port addresses
are used.

This patch now for example allows to specify on the qemu command line:
     -serial mon:stdio -serial /dev/ttyS4
to use the emulated ttyS0 in the guest for console output, and pass
ttyS4 from the host to ttyS1 in the guest.

hppa: Fix serial port pass-through

This series fixes the SeaBIOS-hppa firmware and the serial ports setup code in
qemu so that it reflects the real hardware and allows serial port pass-through
from the host to guests.

Tested with Linux guests.

v2: Changes suggested by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
- Split out hppa_hardware.h restoration to an own patch
- Drop unneccesary checks for serial_hd(x)
