ig4 suspend with devidle set [needs testing]

Thanks for the input. Placing the device in the idle state before suspending
sounds like a good idea. The PCH datasheet does have a note saying this should
be done before any resets so I think you are right. Maybe I missed something
trivial while reading the datasheets, but why in `ig4iic_attach` is this only
done for skylake and not also done for haswell?

I went ahead and added this to a new patch, it would be amazing if someone
could try it out and let me know if it makes any difference. Thanks!
