The DEC version of the Smart controller has its configuration information
stored at a different location in the PCI space, so adjust accordingly.

Also, when using more than two smart controllers in one machine, the

EISA slot base.
- Remove unused IOPORT resource.

Change disk names to `idad' to avoid naming conflicts with the controller,
and enable the new disk code to pick up the drives.
