Third round of IIO new stuff, cleanups and staging graduations for the 3.11
cycle.

1) Add clock consumer support and device tree bindings to adf4350.
   The clock consumer part depends on a not so optional 'optional'
   implementation of clock_round_rate which is not present for pxa27x.
   It will be shortly and as no one actually uses this chip with that
   sub arch as far as we know, no need to delay the inclusion in the
   meantime. See
   http://lkml.indiana.edu/hypermail/linux/kernel/1306.1/00023.html
   for the brief discussion.  This may be the first non soc specific driver
   that makes use of that function.

2) AD7303 DAC new driver.

3) ADIS16130 minor fixes and improvements plus move out of staging.

4) AD7291 improvements to bring it inline with more recent drivers.

5) Update to the sysfs ABI doc to fix some out of date paths.
