Documentation: ABI: add events sampling frequency in sysfs-bus-iio

Some devices have an internal clock used by the events to space the
conversions.
The max1363 introduced the option in
commit 168c9d95a940 ("iio:adc:max1363 move from staging.")
and ad799x in
commit ba1d79613df3 ("staging:iio:ad799x: Use event spec for threshold
hysteresis")
