i2c: Clearly mark ACPI drivers as such

Now that we have ACPI-based SMBus controller drivers, and we will start
telling users to use them instead of native drivers when I/O resources
conflict, I think it would be good to clearly mark ACPI drivers as such
in Kconfig.

This is exactly the same as we just did for hwmon drivers.
