1. Override ISA IRQs 5,6,10,11 as active-low level-triggered.
These are 'wired' to PCI devices.
2. Limit PCI-ISA link routers to route to 5,6,10,11. Others
are active-high edge-triggered and so invalid to use for
PCI devices. In any case, four ISA IRQs is sufficient to
avoid unnecessary aliasing among four links.
Also remove PCI device 0 IRQ info. It's an embedded host bridge with
no interrupt sources.
