- direction of a clean separation between I2C and ISA chip drivers,
- we now have this separate core for ISA ones. It is significantly
- more simple than the real one, of course, because we don't have to
- handle multiple busses: there is only one (fake) ISA adapter.
- It is worth noting that we still rely on i2c-core for some things
