Add a boolean to phylink_config to indicate whether a driver has not been updated for the changes in commit 7cceb599d15d ("net: phylink: avoid mac_config calls"), and thus are reliant on the old behaviour. We were currently keying the phylink behaviour on the presence of a PCS, but this is sub-optimal for modern drivers that may not have a PCS. This commit merely introduces the new flag, but does not add any use, since we need all legacy drivers to set this flag before it can be used. Once these legacy drivers have been updated, we can remove this flag.
