hw/hppa/dino: mask out lower 2 bits of PCI config addr 

some versions of HP-UX 10.20 seems to rely on the fact that DINO
strips out the lower 2 bits of the PCI configuration address.
Also update the binary SeaBIOS distributed to the latest version
from Helge's repository, which is required with that change.
