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 !
