add support for NSC pc87351 SuperIO
add Bitworks/IMS manboard config
This is a very basic framework for the i440bx chipset and the
Bitworks IMS board that uses it. Most things are
structure only.
Known issues:
- SMbus reads to the RAM SPD come back
all zero.
- dump_spd_registers() is commented out since it breaks with
the default setting of generic_dump_spd.c where it wants
2 memory controllers.
