[PATCH] staging: iio: trigger: Use standard attr for sampling frequency

[Daniel Baluta <daniel.baluta@intel.com>]

As written in Documentation/ABI/testing/sysfs-bus-iio the trigger
attribute for sampling frequency should be sampling_frequency.

Fix this for iio-trig-periodic-rtc module in order to prepare it
for moving out of staging.

Jonathan, this module is very useful for devices that do not have
an interrupt pin.

We are working on drivers for such devices and would be very nice to
move this driver in advance to the IIO non-staging location.

What do you say?
