this allows any board to easily setup heater compensation for an
internal compass. The offsets are in body frame (previously in sensor
frame) and are sensor specific using bus device IDs
Having "BIT" in the name gives the impression we are using the macro is
the bit position; however they have the values for those actions, not
the bit position. Rename BIT to VAL to be less confusing.
This is the equivalent of sleep and wait for the conversion time,
after had triggered a new sample request. However it also has the added
benefits of sharing a thread with other sensors on the same bus.
Now we don't read the status register anymore since we have a guaranteed
wait time.
- Make sure device is reset while initializing.
- Give better names to register macros
- Average X, Y and Z by 16: sensor is internally running at 200 sps
(theoretical, ~160 pratical). The wait time is ~6msec averaging
by 16. We do 10msec.
- Inline code that needs to take and release the lock in init()
function, just like other drivers
- Minor changes to coding style and renames to be similar to other
drivers
