Subject: [PATCH net 3/3] net: dsa: mt7530: move setting ssc_delta to PHY_INTERFACE_MODE_TRGMII case

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

Move setting the ssc_delta variable to under the PHY_INTERFACE_MODE_TRGMII
case as it's only needed when trgmii is used.

Fixes: b8f126a8d543 ("net-next: dsa: add dsa support for Mediatek MT7530 switch")
