iio: Move generic buffer implementations to sub-directory For generic IIO trigger implementations we already have a sub-directory, but the generic buffer implementations currently reside in the IIO top-level directory. The main reason is that things have historically grown into this form. With more generic buffer implementations on its way now is the perfect time to clean this up and introduce a sub-directory for generic buffer implementations to avoid too much clutter in the top-level directory.

E.g. if the full voltage is too big for the ADC to handle. Likewise, if an ADC channel measures the voltage across a shunt resistor, with or without amplification, the interesting value is often the current through the resistor. This driver solves these problems by allowing to linearly scale a channel and/or by allowing changes to the type of the channel.
