arm64: dts: lx2160a-cex7: add usb hub

Browse Source 
LX2160A CEX-7 module provides a total of 4 USB ports to the carrier
board, one from first usb controller, and 3 from a hub behind the second
controller.

Both controllers currently have their status set okay in the module's
dtsi file. However devices should be disabled by default when
incomplete.

The first USB controller is only completed by a carrier board featuring
a device or USB connector.

The second controller hosts a USB hub and should therefore be active.

Add description for the USB hub, and enable the first controller only in
the carrier board description.
