arm64: dts: ti: k3-am62x: Add overlays for OV5640

Browse Source 
Three different OV5640 modules are supported using the 15-pin FFC
connector on SK-AM62:
- 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.

These overlays can be used on other boards of the SK-AM62* family that
have a 15/22-pin FFC connector, so we name the overlays with the prefix
k3-am62x-.
