Add the initial support for mx6q/dl udoo boards.

For information about these boards, please visit:
http://www.udoo.org/

In linux.fragment we disable USB support for now because kernel 4.8
hangs on udoo board.

This is been addressed by Peter Chen's kernel patch series that provides
a standard way to reset a USB hub.

When such series hit mainline, then we can bump the kernel and remove
linux.fragment.

Please discard this version. I need to fix an issue and will send a v2.

Thanks

It turns out this issue is not related to the udoo board.

It is commit fad58cefa4a392b ("boot/uboot: allow to build multiple
U-Boot images") that broke SPL installation.

Just sent a patch fixing it.
