PX3 EVB is designed by Rockchip for automotive field,
which intergrated with CVBS(TP2825)/MIPI DSI/LVDS/HDMI
video input/output interface, WIFI/BT/GPS(on a module
named S500 which based on MT6620), Gsensor BMA250E and
light&proximity sensor STK3410.

Changes in v1:
- board rename
- add vendor prefix for i2c interfaced sensors
- use stdout-path to set the default console
