iio: adc: adrv9002_debugfs: add port swich debug interface

Allow to configure RX port switch frequency ranges at runtime. Note that when port switching is set to manual mode, no interfaces are exposed. One also needs to re-initialize the device for the new values to take effect. Signed-off-by: Nuno Sá <[email protected]>
