[PATCH 6/8] arm64: dts: freescale: imx8mm-verdin: Add Toradex OV5640 CSI Cameras

From: Ernest Van Hoecke <ernest.vanhoecke at toradex.com>

Add device tree overlays for the Toradex OV5640 CSI Camera on Verdin CSI_1.

The default overlay describes the current CSI Camera Set 5MP OV5640 with a
27 MHz on-board oscillator. Add a separate 24 MHz overlay for the legacy
camera module.
