arm64: dts: ti: k3-j721e: Add overlay to enable CPSW9G ports in QSGMII mode

Browse source

The J7 Quad Port Add-On Ethernet Card for J721E Common-Proc-Board supports
QSGMII mode. Use the overlay to configure CPSW9G ports in QSGMII mode.

Add support to reset the PHY from kernel by using gpio-hog and gpio-reset.

Add aliases for CPSW9G ports to enable kernel to fetch MAC addresses
directly from U-Boot.
