arm64: dts: ti: beagle*: Add MIT license along with GPL-2.0

Modify license to include dual licensing as GPL-2.0-only OR MIT
license for device trees belonging to BeagleBoard.org Foundation
platforms. 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 copyright year to sync with current year
to indicate license change.

arm64: dts: ti: k3-am625-beagleplay: Add overlays for OV5640

Three different OV5640 modules are supported using the FFC connector on
BeaglePlay:
- Digilent PCam 5C
- ALINX AN5641
- TEVI-OV5640-*-RPI

The Digilent and ALINX modules supply a 12Mhz XCLK to the sensor, while
the TEVI module supplies a 24Mhz XCLK, thus requiring a separate
overlay.
