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.
