i2c-i801: Enable interrupts for all post-ICH5 chips

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.

For now the IDF channels are excluded as I have no idea if they
support interrupts too or not.
