iio: filter: admv8818: Support frequencies >= 2^32

Browse source

[ Upstream commit 9016776f13 ]

This patch allows writing u64 values to the ADMV8818's high and low-pass
filter frequencies. It includes the following changes:

- Rejects negative frequencies in admv8818_write_raw.
- Adds a write_raw_get_fmt function to admv8818's iio_info, returning
  IIO_VAL_INT_64 for the high and low-pass filter 3dB frequency channels.
