arm64: dts: ti: k3-j7200: Add overlay to enable CPSW5G ports in QSGMII mode
The J7 Quad Port Add-On Ethernet Card for J7200 Common-Proc-Board supports
QSGMII mode. Use the overlay to configure CPSW5G ports in QSGMII mode.
Add support to reset the PHY from kernel by using gpio-hog and gpio-reset.
Add aliases for CPSW5G ports to enable kernel to fetch MAC addresses
directly from U-Boot.
