i2c: Add a generic driver to generate ACPI info
Many I2C devices produce roughly the same ACPI data with just things like
the GPIO/interrupt information being different.
This can be handled by a generic driver along with some information in the
device tree.
Add a generic i2c driver for this purpose.
