usb: gadget: net2280: add net2280_match_ep() function
Add 'match_ep' callback to utilize chip-specific knowledge in endpoint matching
process. Function 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.
