There is a minor fault about ACPI enumerated I2C devices with their modalias
attribute. Now modalias is set by device instance not by hardware ID.
For example "i2c:INTABCD:00", "i2c:INTABCD:01" etc.
This means each device instance gets different modalias which does match
with generated modules.alias. Currently this is not problem as matching can
happen also with "acpi:INTABCD" modalias.
Fix this by using ACPI hardware ID.
