iio: Add helper function for initializing triggered buffers Add a helper function for executing the common tasks which are usually involved in setting up a simple software ringbuffer. It will allocate the buffer, allocate the pollfunc and register the buffer.

iio: Fix parameters in iio_triggered_buffer_setup This patch renames the top half handler and the bottom half handler of iio_triggered_buffer_setup() in accordance with their usage. The bottom half has been renamed to reflect the fact that it is a thread based call, compliant with iio_alloc_pollfunc(). The names of the parameters were swapped, thus creating confusion.

iio: add resource managed triggered buffer init helpers Add resource managed devm_iio_triggered_buffer_setup() and devm_iio_triggered_buffer_cleanup() to automatically clean up triggered buffers setup by IIO drivers, thus leading to simplified IIO drivers code.
