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.

3a66946b0f sensor: Rework core to use workqueue API
Remove the homegrown sensor delayed work API in favor of using the
system-wide workqueue.  Drivers still have the option of using their own
fiber.

In a second step, drivers can be refactored to start and use their own
workqueue.

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

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).
