[PATCH] w1: ds2482: add OF device match table

[Kryštof Černý via B4 Relay]

From: Kryštof Černý <cleverline1mc@xxxxxxxxx>

Add an of_device_id table and hook it into the i2c driver so the
ds2482/ds2484 can be matched and auto-probed from Device Tree.

This allows automatic module loading when instantiated via DT.

The ds2482 driver currently lacks an OF match table, which prevents
automatic driver binding and module autoload when the device is
described via Device Tree using compatible strings defined in the
binding.

Even with a correct "maxim,ds2482" compatible, the driver is not
matched because no of_device_id table is registered.

Add OF match support for ds2482/ds2484 and hook it into the i2c driver
to enable proper Device Tree based probing and autoloading.
