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.
