Jessica Clarke 0efad4aceb bhyve: Support legacy PCI interrupts on arm64
This allows us to remove various #ifdef hacks and enable building more
PCI devices.

Note that a hole is left in the interrupt mapping for the RTC rather
than having the two core devices straddle the PCIe interrupts. QEMU's
virt machine also takes this approach.
