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.
