[PATCH 2/2] mfd: tps6105x: Add OF device ID table

[Javier Martinez Canillas <javier@osg.samsung.com>]

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have a
OF device ID table if the devices are registered via OF.

The compatible strings don't have a vendor prefix because that's how it's
used currently, and changing this will be a Device Tree ABI break.
