bjh21 205186731b Substantial overhaul of podule IDs. Unlike on PCI or USB, podule IDs are
assigned by RISCOS Ltd (and were assigned by Acorn) to be unique across all
manufacturers.  This means that associating each one with a manufacturer (and
checking the manufacturer when attaching) is bogus.  Thus, we don't do that
any more.

This should have the pleasant side-effect of getting APDL IDE interfaces
working, since they're just ICS ones with a different manufacturer ID.
