[PATCH 1/3] staging:iio:ad2s1210: Add channel for fclkin and fexcit

The ad2s1210 does not contain any channel for the fclkin and fexcit. As a result, it uses IIO_DEVICE_ATTR to expose this information. This patch adds one channel for fclkin and another for fexcit. It also adds an enum to easily address the correct channel. Signed-off-by: Rodrigo Siqueira
