iio: trigger: Introduce IIO hrtimer based trigger
This patch registers a new IIO software trigger interrupt source
based on high resolution timers.
Notice that if configfs is enabled we create sampling_frequency
attribute allowing users to change hrtimer period (1/sampling_frequency).
The IIO hrtimer trigger has a long history, this patch is based on
an older version from Marten and Lars-Peter.
