iio: frequency: adf4350: Use devm_* APIs
devm_* APIs are device managed and make code simpler. This also takes care of missing clk_put function calls implicitly. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Cc: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
