arm64: dts: ti: k3-j721e: Add MIT license along with GPL-2.0

Modify license to include dual licensing as GPL-2.0-only OR MIT
license for SoC and TI evm device tree files. This allows for Linux
kernel device tree to be used in other Operating System ecosystems
such as Zephyr or FreeBSD.

While at this, update the GPL-2.0 to be GPL-2.0-only to be in sync
with latest SPDX conventions (GPL-2.0 is deprecated).

While at this, update the TI copyright year to sync with current year
to indicate license change (and add it at least for one file which was
missing TI copyright).

arm64: dts: ti: k3-j721e: Add overlay to enable CPSW9G ports with GESI

The J7 GESI EXP board for J721E Common-Proc-Board supports RGMII mode.
Use the overlay to configure CPSW9G ports in RGMII-RXID mode.

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