[PATCH] i2c-nforce2: Add support for MCP67, MCP73 and MCP79

[Jean Delvare]

The MCP79 appears 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.

Testers welcome, of course.

 Datasheet: not publicly available, but seems to be similar to the
            AMD-8111 SMBus 2.0 adapter.
