2d7ae8b249 sensor: migrate all drivers to new error code standard
Check if return value is negative when checking for errors, instead of
checking if it's 0.

df20e3e4a7 sensor: add support for *_ANY get channel
Update all drivers that have vectorial data to return all 3 channels (X,
Y and Z) if the chan parameter is _ANY.
Also fix a compile bug in LSM9DS0 MFD driver.

f169a66205 sensor: migrate all drivers to new SYS_LOG
Refactor all sensor drivers so that they use SYS_LOG instead of
decentralized systems/functions.

f1b95df34e sensor: rename SENSOR_TYPE_* to SENSOR_VALUE_TYPE_*
Rename sensor_value_type enums from SENSOR_TYPE_* to more concludent
name SENSOR_VALUE_TYPE_*. This change is required if we want to
introduce SENSOR_TYPE_* (SENSOR_TYPE_ACCEL - if the sensor/driver
supports accelerometer, SENSOR_TYPE_MAGN - etc.) in the future.
Also it is more clear with this notation what these enums are referring
to.

1be6d1f6c8 sensor: add the posibility to fetch one data type
Now you can specify the sensor type you want to fetch using
sensor_sample_fetch_chan. This will inform the driver that you want only
one type of data updated, leaving the others unchanged and enabling
different sampling rates for multi function devices (MFDs).

0eec9492fc sensors: bma280: fix accel data sample calculation
The values from the accel data sample msb and lsb registers need to
be concatenated (using bitwise or) and not added, since together they
represent a single 14-bit value.

acceleration measurement range instead of defining LSB values for each
measurement range.

69793bb320 sensors: use SENSOR_G constant in all accelerometer drivers
Use the SENSOR_G constant from sensor.h in all accelerometer
drivers, instead of having the constant redefined in each
driver header file.

Since GRAVITY_CONST was measured in mili-m/s^2 and SENSOR_G
is measured in micro-m/s^2, some changes to the calculation
of the acceleration data were added.

fe9c947fee sensor: add driver for BMA280 accelerometer
Add device driver for the BMA280 I2C-based triaxial accelerometer
sensor, which supports reading data from the accel-x, accel-y, accel-z
and temperature channels. The driver also has support for data-ready
and any-motion triggers.
