pwm backend to drive leds.
In new Disco releases, the led sysfs api will replace the pwm sysfs
api to drive the tricolor led.
Keep pwm sysfs api for compatibility reasons.
We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file. Having the makefiles
there is misleading since people try to build and realize the build is
broken.
when this is set the board RGB LED will be controlled by MAVLink
instead of internally. This is useful for cases where the LED patterns
and colours needed are specified by an external authority (such as the
OBC organisers)
- Initialize device on hw_init() method, allowing it not to be
present
- Add missing lock
- Add packed attribute to structs
- Move defines to source file
- Add missing semaphore take on bus
- Initialize device on init function rather than constructor: the
constructor may run before I2CDeviceManager is initialized since our
AP_Notify objects are static so it can't be used.
On early versions of minlure an RGB LED was wrongly placed next to the
barometer, causing trouble on it.
Additionally depending on the LED intensity it may be a pain to leave it
turned on for boards supposed to be used for bench testing. This allows
to disable the LED by software so we don't have to remove it.
- got rid of a lot of not needed defines
- allocated channels on init instead of accessing them every time
through the HAL reference
- simpliefied hw_set_rgb()

Due to the way the headers are organized changing a single change in
an AP_Notify driver would trigger a rebuild for most of the files in
the project. Time could be saved by using ccache (since most of the
things didn't change) but we can do better, i.e. re-organize the headers
so we don't have to re-build everything.
