iio: core: Simplify the registration of kfifo buffers
Among all the users of the kfifo buffers, no one uses the INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and simplify a little bit the internals - overall the documentation - by eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by default with kfifo buffers, which will basically mimic what all the "non direct" modes do.
