iio: adc: ad7298: rework external ref setup & remove platform data

Browse source

This change removes the old platform data for ad7298. It is only used to
provide whether to use an external regulator as a reference.

So, the logic is inverted a bit. The driver now tries to obtain a
regulator. If one is provided, then the external ref is used. The rest of
the logic should work as before.
