drivers: Add support for BBC micro:bit LED display

Browse source 
Adds a simple driver to access the 5x5 LED display found on BBC
micro:bit boards. The display is so limited that no effort is done to
try to integrate with the existing console (which would likely make
the display unusable). Instead, dedicated mb_display_* APIs are added
that are specific to this display.
