Add support for Olimex A13-512-SOM board, and this particular design is like A13-SOM-WIFI can mount on-top of A13-SOM.

Cc: Maxime Ripard maxime.ripard@free-electrons.com Signed-off-by: Jagan Teki jagan@openedev.com --- Changes for v2: - Rebase on master - Drop sufix 'wifi' on dts and defconfig files since SOM comes with wifi module by default.
