arm64: dts: imx8mm-beacon: Enable USB Controllers
The i.MX8M Mini has two available USB controllers. On the imx8mm-beacon board, USB1 is routed to a mini-USB port with OTG functionality. USB2 is routed to a USB hub which has three host-only ports connected to it. Signed-off-by: Adam Ford <aford173@gmail.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
