v2 of the driver for Senseair Sunrise 006-0-0007 CO2 sensor.

The driver supports continuous reads of temperature and CO2 concentration
through two dedicated IIO channels. It also supports calibration and error
inspection through the concentration channel ext_info.

Changelog:

v1->v2:
- Add ABI documentation in [3/3]
- [1/3]
  - Address Rob's comments on missing maxItem and add device node label
  - Do not change the pin's polarity description as suggested by Andy due to
    conflicting suggestions
- [2/3]
  - Expand Kconfig symbol name and change driver's name as suggested by Andy
  - Use regmap instead of raw smbus calls as suggested by Andy
  - Take into account minor style comments from Andy
  - Install channel's ext_info to support calibration triggering and enumerate
    calibration modes and error status
  - Matt suggested to use sysfs attributes, but I found the per-channel
    attributes more appropriate. Hope this is good as well.

Thanks
