Add macros to determine IP address length (internal driver types).
This will be used in next patches for nexthops logic.

- Add functions to allocate/delete/set nexthop group
- NOTE: non-ECMP nexthop is nexthop group with allocated size = 1
- Add function to read state of HW nh (if packets going through it)

* Use refcount, instead of uint
* Increment/decrement recount inside get/put
* Fix error path in __prestera_vr_create. Remove unnecessary kfree.
* Make __prestera_vr_destroy symmetric to "create"

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.
