	Second round of IIO cleanups for the 3.10 cycle

	1) A nice little removal of the unwanted private pointer from
	   struct iio_trigger.
	2) Some clean up of the ad799x driver.
	3) Couple of cleanups for the exynos_adc driver and some documentation.
	4) Move the mxs-lradc initialization a little earlier in the driver to avoid
	   wiping out the configuration just after setting it.

	A nice small set of worthy bits and bobs.
