This patchset adds BMP380 variant to the already existing drivers for
the Bosch BMP180/280 pressure sensors.

Patch 1 adds references and sensor id to the devicetree bindings docs.
Patch 2 adds references to the new sensors on the Kconfig file.
Patch 3 is a minor refactor simplifying driver initialization logic
to facilitate the integration of the new sensor variant extending the
information stored in the "chip_info" struct.

Patch 4 adds the basic logic to initialize and read measurements from
the sensor.
Patch 5 adds advanced configurable features such as sampling frequency
and IIR filter through the IIO sysfs ABI.

Changes in v3:
 - Patch 2: Fixed incorrect abbreviation.
 - Patch 3: use dev_err_probe helper to handle error initializing sensor.
 - Patch 4: Fixed kernel test robot warning provoked by missing include.
 - Patch 4: Fixed bug reported by Dan Carpenter <dan.carpenter@oracle.com>.
 - Patch 5: Fixed formatting and typos on multiple comments.
 - Patch 5: Fixed missing boolean initialization reported by
    Andy Shevchenko <andy.shevchenko@gmail.com>.
 - Patch 5: Replaced duplicated comments with a single comment containing
    a brief explantation in a shared location.
 - Patch 5: Dropped incorrect use of unlikely macro.

Changes in v2:
 - Added patch 2 updating Kconfig with references to new sensor.
 - Patch 3 adds changes proposed by Jonathan Cameron <jic23@kernel.org>
    to declutter and unify configuration logic for the different sensors
    extending "chip_info" struct with default configuration parameters.
 - Patch 4: store temperature and pressure adc values on 3 byte array
    instead of using the type __le32. Uses function get_unaligned_le24
    to convert the little-endian encoded 3 byte value to an integer.
 - Patch 4: drops custom macro le16_from_bytes and use get_unaligned_le16.
 - Patch 4: generate masks using GENMASK macro.
 - Patch 4: use FIELD_PREP to generate bitfields for registries.
 - Patch 4: dropped stray formatting change.
 - Patch 5: adds sanity checks in bmp280_read_raw for channel properties
   only available in the BMP380.
 - Patch 5: on bmp280_write_* checks if a problem ocurred committing new
    configuration and tries to restore previous working configuration
    to keep the sensor in a previous working state.
 - Patch 5: refactored bmp380_chip_config to only check for configuration
    errors when a configuration change is detected.
 - Patch 5: improved invalid configuration detection on BMP380 restarting
    measurement loop to force a new measurement after the configuration is
    updated.
