IIO cleanups and fixes from Jonathan:

"4th set of IIO driver updates and new functionality for the 3.8 cycle.

2 drivers going through final cleanup and moving out of staging.

Addition to the core of support for multiple buffers from a single
datastream.  This functionality is core in allowing multiple users
of interrupt driven data streams from the devices.  First user
will shortly be an input bridge driver.  This has been in review
/ revision for over a year resulting in a far cleaner result.
Much of the work had been in precursor patches. Here we just
add the buffer set tear up and down support + switch to multiple
buffer pushing in the drivers (a one line change in all users).
Thanks to those who have tested / reviewed this set."
