net: marvell: prestera: Add prestera router infra 



Add prestera_router.c, which contains code to subscribe/unsubscribe on
kernel notifiers for router. This handle kernel notifications,
parse structures to make key to manipulate prestera_router_hw's objects.

Also prestera_router is container for router's objects database.
