On chipsets with a second 'Integrated Device Function' SMBus controller use
a different adapter-name for the second IDF adapter.
This allows platform glue code which is looking for the primary i801
adapter to manually instantiate i2c_clients on to differentiate
between the 2.
This allows such code to find the primary i801 adapter by name, without
needing to duplicate the PCI-ids to feature-flags mapping from i2c-i801.c.
