Subject: [PATCH net-next 19/24] net: dsa: mt7530: remove .mac_port_config for MT7988 and make it optional

From: Arınç ÜNAL <arinc.unal@...nc9.com>

For the switch on the MT7988 SoC, the code in mac_port_config for MT7988 is
not needed as the interface of the CPU port is already handled on
mt7988_mac_port_get_caps().

Make .mac_port_config optional. Before calling
priv->info->mac_port_config(), if there's no mac_port_config member in the
priv->info table, exit mt753x_mac_config() successfully.

Remove mac_port_config from the sanity check as the sanity check requires a
pointer to a mac_port_config function to be non-NULL. This will fail for
MT7988 as mac_port_config won't be a member of its info table.
