OK, this I seriously dislike. Hence a question ... my feeling is the XHCI and 
EHCI code for handling multiple controllers and multiple ports is almost the 
same. Can this code be adjusted to handle both EHCI and XHCI controllers 
indiscriminately ?

This would result in having CONFIG_USB_MAX_CONTROLLER_COUNT 3 on this board and 
being able to use both EHCI and XHCI . Would this be possible for you to 
implement please ? Thanks !
