mx6sx: Add initial support for UDOO Neo Board
UDOO Neo Board is a development board from Seco that has three models:
- UDOO Neo Basic
- UDOO Neo Basic Kick Starter
- UDOO Neo Extended
- UDOO Neo Full
All versions are based on the i.MX6 SoloX processor.

This work is based on a previous commit of Francesco Montefoschi
