mlxsw: spectrum: Add support for auto-negotiation disable mode
In 'auto-neg off' the device have sent AN (auto-negotiation) frames
with the forced speed. Thus, fix it using an_disable_admin field in
Port type and speed (PTYS) register. This field indicates if speed
negotiation frames would be send by the port or not.
Add the field and enable/disable it for 'auto-neg on/off', make the
port to start/stop sending AN (auto-negotiation) frames. Note that for
SwitchX2 the behavior doesn't change (i.e support only AN enabled with
forced speed).
