netpoll: Introduce netpoll_carrier_timeout kernel option
Some PHYs require longer timeouts for carrier detection, and auto-negotiation process may take indefinite amount of time. It may be inconvenient to force longer timeouts for sane PHYs, so let's introduce a kernel command line option. Since we're using module_param(), the option also can be changed in runtime.
