To reproduce this issue, you can modify board .dts file to set
as the following to build u-boot binary.
usb0 = /usb@c500;
usb1 = /usb@c5008000;
Install device on USB1 port (address at 0xc500).
And run usb reset
to proceed
later device enumeration.

Therefore we add a definition in header file
.

Add support for command line usb reset or usb start to initialize
, usb stop to stop multiple USB controllers at once.
Other commands like usb tree also support multiple controllers.
New added definitions in header file are:
