iio: core: Introduce IIO configfs support
This patch creates the IIO configfs root group. The group will appear under <mount-point>/iio/, usually /config/iio. We introduce configfs support in IIO in order to be able to easily create IIO objects from userspace. The first supported IIO objects are triggers introduced with next patches.
