iio: adc: vf610: implement configurable conversion modes
Support configurable conversion mode through sysfs. So far, the mode used was low-power, which is enabled by default now. Beside that, the modes normal and high-speed are selectable as well. Use the new device tree property which specifies the maximum ADC conversion clock frequencies. Depending on the mode used, the available resulting conversion frequency are calculated dynamically.
