ARM: dts: am335x-sl50: 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.
