	Third round of IIO cleanups, graduations and new stuff for the 3.10 cycle.

	A small set including 3 things.
	1) A short cleanup series for the ak8975.
	2) Graduation of ak8975 out of staging.
	3) Some additional bits for the at91 adc driver to cover low resolution
	   modes, sleep and a little bit of missing documentation.
