iio: pressure: Add driver for Honeywell ABP family
This patch adds minimal driver for the Honeywell Amplified Basic
Pressure sensors series. Sensors are pretty simple but are
available in many variants:
- psi/mbar/kPa output,
- analog/i2c/spi,
- gage/differential measurement,
- different measure ranges etc.
Refer to datasheets for more details:

http://sensing.honeywell.com/index.php%3Fci_id%3D45841
Driver internals:
- i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c
bus doesn't support it, it is required to send a dummy byte to trigger
measurement,
- since iio sysfs expects kilopascals, mbar-variants are treated as their
respective kPa-s, hence i2c id-table has doubled entries in one line:
{ "abp060mg", ABP006KG }, { "abp006kg", ABP006KG },
- psi-variants have prescaled values in config,
- no temperature reads yet.
Work remained:
- optional temperature channel,
- SPI support,
- DT binding.
Changes since v1:
- mutex is now locked in read_raw(),
- corrected error codes,
- fixed coding style issues,
- renamed few defines and functions abp -> abp060mg
(some structs left as they were to keep the sensible meaning).
