usbdebug: Support choice of EHCI controller

Browse Source 
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.

Some boards have multiple EHCI controllers with possibly only
one having the Debug Port capability on an external USB port.
Mapping of this index to PCI device functions is southbridge
specific and mainboard level Kconfig should already provide
a working default value here.
