Bjorn Helgaas 9e6866686b x86/mpparse: Account for bus types other than ISA and PCI
In commit f8924e770e ("x86: unify mp_bus_info"), the 32-bit
and 64-bit versions of MP_bus_info were rearranged to match each
other better.  Unfortunately it introduced a regression: prior
to that change we used to always set the mp_bus_not_pci bit,
then clear it if we found a PCI bus.  After it, we set
mp_bus_not_pci for ISA buses, clear it for PCI buses, and leave
it alone otherwise.

In the cases of ISA and PCI, there's not much difference.  But
ISA is not the only non-PCI bus, so it's better to always set
mp_bus_not_pci and clear it only for PCI.

Without this change, Dan's Dell PowerEdge 4200 panics on boot
with a log indicating interrupt routing trouble unless the
"noapic" option is supplied.  With this change, the machine
boots reliably without "noapic".
