Add support for 64-bit image drawing with MAX7219 8x8 LED Matrix

Browse source 
The MAX7219 driver has been extended to add support for bitmap drawing
on an 8-by-8 LED matrix panel. Consumers can specify the targeted chip,
which corresponds to a LED matrix panel, and provide a 64-bit image
buffer specifying the pixels which should illuminate.
