This represents essentially a complete rewrite of the ISA PnP code. The

new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.

This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.
