[PATCH v2 0/3] staging:iio:ad2s1210: Rework read/write operation for fclkin and fexin

[Rodrigo Siqueira]

This patchset changes the way that frequency of clock input (fclkin) and
the excitation frequency (fexcit) are exposed to the userspace. The
original code uses the IIO_DEVICE_ATTR to export the configuration of
fclkin and fexcit to the userspace which is not in agreement with the
current ABI. This patchset adds one channel per clock configuration,
updating the read_raw function by adding a handler for the new channels,
and introduces the write_raw function.  Furthermore, this patchset
removes the legacy code responsible for the read and write operation
related to fclkin and fexcit. Finally, this patchset uses parts of the
original code for handling frequency configuration as an attempt to
avoid problems.

Changes in v2:
 - Removes unnecessary switch case in the write_raw function.
 - Replaces the use of goto for direct return.
 - Removes definition with string.
 - Removes unecessary label.
