mini-x-1gb: Add support for the mini-x-1gb board

Add support for the new 1 Gig RAM mini-x a10 systems. Note these also come
with a new pcb layout. Pictures of the old PCB (2 revisions):

The new pcb for (my) 1GB version:

You can also see the difference between the 2 without opening the mini-x
up, as the order of the connectors has been changed (more or less mirrored):

Where the old 512MB mini-x, viewed from the rear has:
<hdmi> (a) (w) (d)

The new 1GB has:
(d) (w) (a) <hdmi>

a: av plug, w: wifi antenna, d: dc plug

Also note that the otg and host connectors have swapped place too, but the
frontplate was not updated, so to get the (much more usable) host port, you
must plug the cable into the USB connector labelled OTG!
