[PATCH] mfd: axp20x-i2c: Add i2c-ids to fix module auto-loading

[hdegoede@redhat.com (Hans de Goede)]

The i2c subsys does not load modules by compatible, only by
i2c-id, with e.g. a modalias of: "i2c:axp209".

Populate the axp20x_i2c_id[] table with supported ids, so that
module auto-loading will work.
