i2c-nforce2: Add support for MCP67, MCP73, MCP78S and MCP79 



The MCP78S and MCP79 appear to be compatible with the previous nForce
chips as far as the SMBus controller is concerned. The MCP67 and MCP73
were not tested yet but I'd be very surprised if they weren't
compatible too.

Datasheet: not publicly available, but seems to be similar to the

           AMD-8111 SMBus 2.0 adapter.
