Fourth set of IIO new device support, features and cleanups for the 4.12 cycle

New device support
* max1117, 1118 and 1119
  - new ADC driver
* max9611
  - new ADC driver
* pm8xxx hk/xoadc
  - new driver with some shared features broken out from the SPMI vadc.
* sun4i-gpadc
  - A33 thermal sensor support (with associated rework)
* stm32-dac
  - new driver and bindings
* stm32 trigger
  - enable support of quadrature encoder device and counter modes

Features
* apds9960
  - use the runtime pm for normal suspend
* stm32-adc
  - add opition to sest resolution via devicetree
* xoadc
  - augment DT bindings to deal with some weird mux cases

Cleanups
* ad5933
  - protect direct mode using claim and release helpers
* ade7759
  - S_IRUGO and friends to octal in two goes
* adis16203
  - drop unnecessary brackets
* hid-sensor
  - fix unbalanced pm_runtieme_enable error when probing after remove
* lsm6dsx
  - use actual part numbers for device name when known
  - simplify data read pin parsing
* mpu3050
  - avoid double reporting errors
