ARM: dts: imx6qdl-udoo: Enable USB host

Commit 8f2ca252 ("ARM: dts: imx6qdl-udoo: Disable USB host to
work around boot issues") disabled USB host to avoid boot hang.

Properly describe the USB2514 USB hub to fix this issue.

Tested on a imx6q-udoo board and verified that it boots fine
and USB host functionality works.
