bios: allow qemu to configure irq0->inti2 override
Win2k8 expects the HPET interrupt on inti2, regardless of whether
an override exists in the BIOS. And the HPET spec states that in legacy mode,
timer interrupt is on inti2.
The irq0->inti2 override will always be used unless the kernel cannot do irq
routing (i.e., compatibility with old kernels). So if the kernel is capable,
userspace sets up irq0->inti2 via the irq routing interface, and adds the
irq0->inti2 override to the MADT interrupt source override table,
and the mp table (for the no-acpi case).
Changes from v8 - Incorporated Gleb's comments to patch 1/5 and 4/5.
In 1/5, removed a "return" per Gleb's comment.
See 4/5 for v8->v9 change description.
This series doesn't boot for me - Linux says the 8254 is not connected
to ioapic. I pushed it as the 'hpet' branch again, can you take a look?
