Subject: [RFC/RFT PATCH net-next 4/4] net: dsa: microchip: remove unused dev->dev_ops->phylink_mac_config()

The history is that Arun first added a phylink_mac_config()
implementation for lan937x_dev_ops in commit a0cb1aa43825 ("net: dsa:
microchip: lan937x: add phylink_mac_config support"), then in commit
f3d890f5f90e ("net: dsa: microchip: add support for phylink mac
config"), that implementation became common for all switches, but the
dev_ops->phylink_mac_config() function pointer remained there, even
though there is no switch-specific handling anymore.
