staging:iio:adc:ad7280a: Make oversampling_ratio a runtime control

Browse source

Oversampling has nothing directly to do with analog circuits or
similar so belongs in the control of userspace as a policy decision.

The only complexity in here was that the acquisition time needs
updating if this setting is changed at runtime (as oversampling
is time consuming).
