In pc_q35.c the PCI host bridge's io and memory space is initialized
with get_system_memory() and get_system_io() respectively. Therefore,
using pci_address_space() and pci_address_space_io() is equivalent. All
in all this makes the LPC function respect whatever memory spaces the
PCI bus was set up with.
