[PATCH] Adding minimal support for the UDOO board.

[Raphaël Poggi]

Hum I think I have understand, in fact there is 2 differents type of
UDOO board, one quad and one dual. So I think it is a good idea to add
in imx6qdl-udoo.dtsi a compatible string like "udoo,imx6qdl"
and in the imx6q-udoo.dts a compatible string like "udoo,imx6q" is this right ?

Thanks.
