I2C drivers shouldn't be enabled by default - there is usually no safe
way to find out that I2C devices are present (unlike PCI and USB), so
they should be enabled only where there is some way of discovering that
the I2C devices exist.

However, it appears that this is an exception, because we can find out
about I2C HID devices through ACPI.  So it should be enabled for x86.

You might be able to compile the module but I can't provide simple
instructions for this.

I will enable this for Linux 3.12.
