Subject: [PATCH net-next v3 2/3] net: ethernet: ti: am65-cpsw: Enable QSGMII for J784S4 CPSW9G

TI's J784S4 SoC supports QSGMII mode with the CPSW9G instance of the
CPSW Ethernet Switch. Add a new compatible for J784S4 SoC and enable
QSGMII support for it by adding QSGMII mode to the extra_modes member of
the "j784s4_cpswxg_pdata" SoC data.
