ASoC: adau1701: move firmware download to adau1701_reset()
The chip needs a new download after each reset, so the code to do that needs to live in adau1701_reset(). Signed-off-by: Daniel Mack <zonque@gmail.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
