[PATCH 3/5] board: ten64: remove USB hub references from internal FDT when needed

[Mathew McBride]

More recent revisions of the Ten64 board do not have a USB Hub
(USB5744). The references to the USB5744 need to be removed in U-Boot's
internal FDT to avoid the USB5744 setup being invoked on these boards.
