ARM: dts: hummingboard/cubox-i: add USB OC pinctrl configuration
Hummingboard has no over current hardware, so disable the over current detection for both ports. Cubox-i has over current hardware, so appropriately configure this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
