Initialization was also changed a little bit so we don't try to
initialize 25 times. We rather use the same methods as in the
AP_InertialSensor drivers.
Also move up the call to is_zero() in read_raw so we don't set
_mag_[x|y|z] in case of failure.
These are not used. The only place where raw fields are used are in the
compass calibrator and we don't need to store them.
Additionally remove duplicated documentation about the meaning of the
functions to avoid them getting out of sync.
We still need the BusDriver (in some places called SerialBus) interface
since this driver can also be used on an AuxiliaryBus and that has a
different interface.
- Capitalize and rename constants
- Make clear what gain is applied in calibration and what is the
"normal" gain
- Make the separation between HMC5883L and HMC5843 explicit when it
makes sense to improve readability
- Remove spurious delay in calibrate function

Besides the usual conversion some more improvements:
- Use generic function to convert endianness
- Minor cleanups
- Reorder per-board ifdefs in compass instantiation: distinguish when
there's a default compass to when it should probe other compasses

Not having data ready during initialization is normal. Don't print error
message since it can mislead people to think the compass was not
initialized successfully.
This is the only driver doing this, using the system_initializing() from
scheduler to log selectively. Remove the check together with removal of
unused wrapper methods to semaphore.
Most of AP_Progmem is already gone so we can stop including it in most
of the places. The only places that need it are the ones using
pgm_read_*() APIs.
In some cases the header needed to be added in the .cpp since it was
removed from the .h to reduce scope. In those cases the headers were
also reordered.
