Mark Pizzolato 1af590d806 PDP11, VAX8600, VAX780, VAX750: Fix to auto configure Massbus adapters ...

When a mix of Massbus devices are configured with some enabled and
others disabled, the MBA's need to be allocated and properly configured
in the desired preferred order (RP, TU, RS).  On the PDP11, this interacts
with auto-configure since the RH devices are visible in the Unibus I/O
page.  On the PDP11 the second Massbus device can only be configured
if the TM device is disabled since the auto-configure assigned vectors
overlap for RHB and TM.

Problem originally reported in #301.
