@RobertCNelson @jadonk please review my code :) Everything has been tested on BBBWL and BBAI.

This update brings

1. A new compatibile DT overlay for 4.3" LCD cape (4D Systems GEN4-4DCAPE-43CT-CLB).
2. BBB/BBBWL only DT overlay for 4.3" LCD cape (4D Systems GEN4-4DCAPE-43CT-CLB).
3. Overlays for Bone LED on P8 and P9 header, can be used as template for LED projects.

@RobertCNelson that would be awesome, do you have any reference overlay for me to look at?

Also, are these changes are in effect already? if I update my board will I get all this new code?
I want to start working on the display stuff again :)
