ASoC: samsung: Use iio_get_channel_type() accessor.

struct iio_chan_spec is meant to be opaque to IIO consumer drivers
which should only use the interfaces in linux/iio/consumer.h.
Use the provided accessor function to find get the type of the
channel instead of directly reading it form the structure.
