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.
