Add 'match_ep' callback to utilize chip-specific knowledge in endpoint matching process. Functions does the same that was done by chip-specific code inside of epautoconf. Now this code can be removed from there to separate generic code from platform specific logic.

This string of *if* statements is asking to be *switch* instead.
