We have two trivial IRQ routines, a single statement and a real function -
relocate them. While we are at it kill the trivial to sort out soft reset
and slv bits in the same areas of code.

Simple example of how a gpio trigger driver would work.

The original posting of this driver led to a discussion in
which it was commented that a better system was needed
for dealing with the many possible periodic interrupt
sources available on some SoCs.  Unfortunately that is
a big task and as far as I know, no-one has taken it
on as yet.  So in the meantime this driver is still
in here.

Example of relatively common case of device sampling
based on internal clock and providing a data ready
signal to indicate that new data is available to be
read out.

Generic trigger approach used to allow other devices
to be sampled 'at the same time' as this the accelerometer.
This is very useful in various motion estimation algorithms.
