Johan Hedberg d7a189d2ec drivers: display: mb_display: Unify image and string APIs
Both the string and image rendering may want to take advantage of
scrolling and sequential display capabilities. Consolidate the APIs so
that there's a single one for images (mb_display_image) and a single
one for strings (mb_display_print). Both take a duration parameter for
the per-frame duration as well as a mode parameter which specifies
sequential vs scrolling behavior as well as an optional looping flag.

Johan Hedberg 7e5df0cc02 drivers: display: Enhance BBC micro:bit string output capabilities
Add a new mb_display_print() API which takes printf-style parameters
and outputs scrolling text instead of one character at a time. The
existing mb_display_str() API is renamed to mb_display_string() for
consistency, and now also takes printf-style parameters.

Johan Hedberg 380d24de1d drivers: Add support for BBC micro:bit LED display
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.
