First set of IIO fixes for the 5.1 cycle.

Mostly the usual mix, but the bme680 SPI fix is much larger than
I would normally like.  It never worked, but conversely we have
code there that would make people expect it to do so.  Chances
of side effects are very low.

* core
  - Fix an uninitialised bitaks that could potentially result in random
    channels being enabled on startup.
* ad7192
  - Fix a wrong channel address for ad7193.
* ade7854
  - Fix a typo that results in returning peak voltage instead of peak current.
* at91
  - Fix a potential hang due to a race on interrupt setting.
* bmg160
  - Fix scale factor of temperature
* bme680
  - Fix scale factor of temperature
  - Fix SPI read interface.  This is a bit of a large patch as it seems
    that it never worked.  It's major for this driver but is unlikely to
    have any negative side effects.
* kxcjk1013
  - restore sensor range setting after resume.
* mcp4725
  - make sure to store powerdown bits when storing to the eeprom.
* mpu3050
  - Mask the chip ID correctly as we have chips that set the bother bits of
    this register.
* sgp30
  - Fix a missing Kconfig block that means the driver doesn't actually ever
    get built.
