Kernel/PCI: Move IO based HostBridge code to x86 arch-specific directory

Browse Source 
The simple PCI::HostBridge class implements access to the PCI
configuration space by using x86 IO instructions. Therefore, it should
be put in the Arch/x86/PCI directory so it can be easily omitted for
non-x86 builds.
