Add inetaddr notifiers to support add/del IPv4 address on switchdev
port. We create TRAP on first address, added on port and delete TRAP,
when last address removed.
Currently, driver supports only regular port to became routed.
Other port type support will be added later

Initial implementation of notification handlers. For now this is just
stub.
So that we can move forward and add prestera_router_hw's objects
manipulations.
We support several addresses on interface. We just have nothing to do for
second address, because rif is already enabled on this interface, after
first one.

Add prestera_router_hw.c. This file contains functions, which track HW
objects relations and links. This include implicity creation of objects,
that needed by requested one and implicity removing of objects, which
reference counter is became zero.
We need this layer, because kernel callbacks not always mapped to
creation of single HW object. So let it be two different layers - one
for subscribing and parsing kernel structures, and another
(prestera_router_hw.c) for HW objects relations tracking.
There is two types of objects on router_hw layer:
- Explicit objects (rif_entry) : created by higher layer.
- Implicit objects (vr) : created on demand by explicit objects.

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.
