I did not receive a single bug report after interrupt support was
added for a limited number of chips. So I'd say the code is good and
should be enabled for all supported chips, that is: ICH5 and later.

I was able to test on Patsburg IDF channels and although I couldn't
test all transaction types, interrupts seem to work the same as on the
main SMBus channel so let's enable interrupts there too.
