Subject: [RFC PATCH 8/8] iio: event_monitor: Add support for activity channel

We have the following testing scenario:

$ insmod iio_dummy_evgen.ko
$ insmod iio_dummy.ko

$ ./iio_event_monitor /dev/iio:device0
Event: time: 1412254756207353948, type: voltage, channel: 0, evtype: thresh, direction: rising
Event: time: 1412254762455172908, type: activity(running), channel: 0, evtype: motion, direction: rising
Event: time: 1412254770823830774, type: activity, channel: 0, evtype: step_detect, direction: rising

$ echo 0 > /sys/bus/iio/devices/iio_evgen/poke_ev0
$ echo 1 > /sys/bus/iio/devices/iio_evgen/poke_ev0
$ echo 2 > /sys/bus/iio/devices/iio_evgen/poke_ev0
