bhyve: Make most I/O port handling specific to amd64

Description

bhyve: Make most I/O port handling specific to amd64

  • The qemu_fwcfg interface, as implemented, is I/O port-based, but QEMU implements an MMIO interface that we'll eventually want to port for arm64.
  • Retain support for I/O space PCI BARs, simply treat them like MMIO BARs for most purposes, similar to what the arm64 kernel does. Such BARs are created by virtio devices.
