Fix iio header files kernel-doc notation errors, spelling, typos,
indentation, grammar, etc.
It would also be good if these function names were spelled
correctly, but I didn't change them:
iio_push_or_escallate_ring_event()
iio_trigger_dettach_poll_func()

Add general registration support for IIO triggers. These
are currently only used to initialize a 'poll' of a given
device. Examples include the lis3l02dq's data ready signal
being used to initialize a read and gpio triggers being
used to allow externally synchronized sensor reading.
Each trigger can cause any number of 'consumer' devices
to be polled with each storing data into a related ring
buffer.
Two stage triggering is supported with 'fast' and 'slow'
paths. The first is used for things like pulling a data
hold line high and the second for actual read which
may take far longer.
Changes since V2:
* As with IIO triggers now use a registration approach
much closer to that of input leading to cleaner code.
