Subject: arm64: dts: k3-am625-verdin-wifi-dev-u-boot: ethernet support

Integrate Ethernet support.

Note: Due to U-Boot not support pinctrls in the cpsw3g_midio node they
      were all added to the cpsw3g node. And due to U-Boot currently not
      supporting Ethernet PHY reset-gpios we just GPIO hog it.

Upstream-Status: Pending

Initial U-Boot to be used for bring-up and validation of the V1.0
design, we'll decide on the step forward to mainline this once the
bring-up and validation will be done.
