iio: dummy: Add virtual registers for dummy device
We need a way to store events generated by iio_dummy_evgen module,
in order to correctly process IRQs in iio_simple_dummy_events.
For the moment, we add two registers:
* id_reg - ID register, stores the source of the event
* id_data - DATA register, stores the type of the event
e.g echo 4 > /sys/bus/iio/devices/iio_evgen/poke2
id_reg 0x02, id_data 0x04
This means, event of type 4 was generated by fake device 2.
We currently use a hardcoded mapping of virtual events to IIO events.
