board: Add Toby-Churchill SL50 board support.
Add support for Lightwriter SL50 series board, a small, robust and portable Voice Output Communication Aids (VOCA) designed to meet the particular and changing needs of people with speech loss resulting from a wide range of acquired, progressive and congenital conditions.

The AM335x SoC has a total of 6 UARTs (UART0 to UART5 as referenced
|
||||
in documentation, etc) available to it. Depending on your specific
|
||||
board you may want something other than UART0 as for example the IDK
|

uses UART3 so enter 4 here.
