verdin-am62: ov5640: Add overlays for camera modules with 27MHz oscillators
The Toradex Arducam OV5640 module uses a 27MHz on-board crystal
oscillator for its camera clock, while the current overlays assume the
camera clock is 24MHz. This creates a 10% clock discrepancy for the
module, affecting camera frame rate. Add dedicated overlays to support
the Arducam OV5640.
