mlxsw: Introduce Mellanox SwitchX-2 ASIC support



Benefit from the previously introduced Mellanox Switch infrastructure and
add driver for SwitchX-2 ASIC. Note that this driver is very simple now.
It implements bare minimum for getting device to work on slow-path.
Fast-path offload functionality is going to be added soon.
