[PATCH v2 00/50] hppa: general improvements and tidy-ups

[Mark Cave-Ayland]

This patchset started off when I noticed that dino.c was accessing parent_obj
directly rather than using a QOM cast. After fixing that I noticed quite a few
other improvements that could be done to bring hppa up to our recommended
coding standards.

The main aim of this patchset is to de-couple the dino and lasi devices from
the board using QOM to handle the initialisation instead of having global
device init functions. Included in this is switching the onboard devices
over to use qdev GPIOs for wiring instead of directly allocating QEMU IRQs.

Along the way I've renamed the board config from CONFIG_DINO to
CONFIG_HPPA_B160L since that better represents the machine type, and then
used CONFIG_DINO and CONFIG_LASI for the appropriate devices which have been
moved to hw/pci-host/dino.c and hw/misc/lasi.c respectively.

After the reorganisation it was trivial to remove hppa_sys.h and the majority
of pci.c which wasn't being used. Finally I tidied up the use of the QOM
machine type macros in machine.c.

The result has been lightly tested with a tiny Linux image I had lying around
for testing my recent ESP changes, so more testing is welcome. There is a bit
more work to be done sorting out the lasips2 device init and machine init, but
since the patchset is already quite big I can follow up with that once this
series has been merged.

v2:
- Rebase onto master
- Add R-B tag to patch 1 from Richard
- Add A-B tag from Helge to entire series
- Update patch 12 to use CONFIG_HPPA_B160L instead of CONFIG_HPPA_GENERIC and
  also update the machine description
