First set of IIO fixes for the 4.2 cycle.

* Fix a regression in hid sensors suspend time as a result of adding runtime
  pm.  The normal flow of waking up devices in order to go into suspend
  (given the devices are normally suspended when not reading) to a regression
  in suspend time on some laptops (reports of an additional 8 seconds).
  Fix this by checking to see if a user action resulting in the wake up, and
  make it a null operation if it didn't.  Note that for hid sensors, there is
  nothing useful to be done when moving into a full suspend from a runtime
  suspend so they might as well be left alone.
* rochip_saradc: fix some missing MODULE_* data including the licence so that
  the driver does not taint the kernel incorrectly and can build as a module.
* twl4030 - mark irq as oneshot as it always should have been.
* inv-mpu - write formats for attributes not specified, leading to miss
  interpretation of the gyro scale channel when written.
* Proximity ABI clarification.  This had snuck through as a mess.  Some
  drivers thought proximity went in one direction, some the other.  We went
  with the most common option, documented it and fixed up the drivers going
  the other way.  Fix for sx9500 included in this set.
* ad624r - fix a wrong shift in the output data.
* at91_adc - remove a false limit on the value of the STARTUP register
  applied by too small a type for the device tree parameter.
* cm3323 - clear the bits when setting the integration time (otherwise
  we can only ever set more bits in the relevant field).
* bmc150-accel - multiple triggers are registered, but on error were not being
  unwound in the opposite order leading to removal of triggers that had not
  yet successfully been registered (count down instead of up when unwinding).
* tcs3414 - ensure right part of val / val2 pair read so that the integration
  time is not always 0.
* cc10001_adc - bug in kconfig dependency. Use of OR when AND was intended.
