iio: adc: ad4695: make ad4695_exit_conversion_mode() more robust
Ensure that conversion mode is successfully exited when the command is
issued by adding an extra transfer beforehand, matching the minimum CNV
high and low times from the AD4695 datasheet. The AD4695 has a quirk
where the exit command only works during a conversion, so guarantee this
happens by triggering a conversion in ad4695_exit_conversion_mode().
Then make this even more robust by ensuring that the exit command is run
at AD4695_REG_ACCESS_SCLK_HZ rather than the bus maximum.
