Alexandru Ardelean 5483b8d501 iio: adc: ad7887: invert/rework external ref logic
This change inverts/reworks the logic to use an external reference via a
provided regulator.

Now the driver tries to obtain a regulator. If one is found, then it is
used. The rest of the driver logic already checks if there is a non-NULL
reference to a regulator, so it should be fine.
