MLK-20395 DTS: imx: Add alias for usb1 device
Some platforms don't have alias for usb1 device, so when initialize the
second controller, its seq is allocated by u-boot automatically.
This introduces a problem if the initialization of first controller is failed,
for example nothing connect to first controller, then the seq allocated
for second controller is 0 not 1. EHCI driver uses the seq as index for
USB controller and phy, so it will cause initialization problem for second
controller.
Fix the issue by adding the usb1 alias for second USB controller.
