iio: adc: ad9467: don't allow reading vref if not available

Browse source

If there's only one possible scale, there's no way to change the Vref
select in the device so avoid reading the register in ad9467_get_scale().
In this case, it makes no sense to provide the .read_available()
callback nor allowing for writing the scale attribute.

Note this is in preparation for supporting a new device that only has
one possible scale.
