description:
On Armada 7k/8k and CN913x, there are two host and one device USB controllers.
Each of two exiting UTMI PHYs could be connected to either USB host or USB device
controller.
The USB device controller can only be connected to a single UTMI PHY port
0.H----- USB HOST0
UTMI PHY0 --------/
0.D-----0
\------ USB DEVICE
1.D-----1
UTMI PHY1 --------\
1.H----- USB HOST1
