Right. I thought to do so is easy, but that turned out to reveal a lot
of other issues:

- hppa is using the I8259 code, which relies on ISA
- hw/hppa/pci.c seems to only contain unused stuff
- LASI use hw/char/parallel.c, which relies on ISA. parallel.c could
  propably be split up into a ISA dependent part and a generic part

So it is more work to remove ISA completely, therefore i'll drop that
patch for now and submit it later again.

Thanks
Sven
