Intrusion status detection via Interrupt Status Register.

Signed-off-by: Ivan Mikhaylov <redacted>

I think this should, if at all, be handled using the
iio->hwmon bridge (or, in other words, require a solution
which is not chip specific).

Thanks a lot for suggestion, it's actually looks what's needed here instead of
this driver. Anyways, there is no IIO_PROXIMITY support inside supported types
in iio_hwmon.c. Should I add additional case inside this driver for
IIO_PROXIMITY type?

I am also not sure if "proximity" is really appropriate to use
for intrusion detection in the sense of hardware monitoring.
This would require a proximity sensor within a chassis, which
would be both overkill and unlikely to happen in the real world.
"Intrusion", in hardware monitoring context, means "someone
opened the chassis", not "someone got [too] close".

I'm not sure either but it exists :) And it's exactly for this purpose:
"someone opened the chassis", "how near/far is cover?".
