Move the hostb driver out of the i386 and amd64 PCI code (where it was

duplicated anyways) and into a single MI driver.  Extend the driver a bit
to implement the bus and PCI kobj interfaces such that other drivers can
attach to it and transparently act as if their parent device is the PCI
bus (for the most part).
