First set of IIO fixes for the 4.13 cycle.

* ad2s1210
  - Fix negative angular velocity reads (identified by a gcc 7 warning)
* aspeed-adc
  - Wait for initialization sequence to finish before enabling channels.
  Without it no channels work.
* axp288
  - Revert a patch that dropped some bogus register mods.  No one is entirely
  sure why but it breaks charging on some devices.
  - Fix GPADC pin read returning 0. Turns out a small sleep is needed.
* bmc150
  - Make sure device is restored to normal state after suspend / resume
  cycle.  Otherwise, simple sysfs reads are broken.
* tsl2563
  - fix wrong event code.
* st-accel
  - add spi 3-wire support. Needed to fix the lsm303agr accelerometer
  which only had 3 wires in all cases.  Side effect is to enable optional
  3-wire support for other devices.
* st-pressure
  - disable multiread by default for LPS22HB (only effects SPI)
* sun4i-gpadc-iio
  - fix unbalanced irq enable / disable
* vf610
  - Fix VALT slection for REFSEL bits - ensures we are using the
  right reference pins.
