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.
