arm64: dts: ti: k3-am62-verdin: Add Toradex OV5640 CSI Cameras

Add device tree overlays for the Toradex OV5640 CSI Cameras on Verdin
CSI_1. Two variants are supported: the current CSI Camera Set 5MP OV5640
with a 27 MHz oscillator and the legacy CSI Camera Module 5MP OV5640
with a 24 MHz oscillator.
