sfc: Simplify PHY polling
Falcon can generate events for LASI interrupts from the PHY, but in practice we have never implemented this in reference designs. Instead we have polled, inserted the appropriate events, and then handled the events later. This is a waste of time and code. Instead, make PHY poll functions update the link state synchronously and report whether it changed. We can still make use of the LASI registers as a shortcut on the SFT9001.
