usbdebug: Support choice of EHCI controller

Nowadays, chipsets or boards do not only have one USB port with the
    capabilities of a debug port but several ones. Some of these ports are
    easier accessible than others, so making them configurable is also necessary.
    This change adds infrastructure to switch between EHCI controllers,
    but does not implement it for any chipset.
