[PATCH v2 4/4] arm64: dts: imx8qxp-mek: add parallel ov5640 camera support

[Frank Li via B4 Relay]

From: Frank Li <Frank.Li@xxxxxxx>

Add parallel ov5640 nodes in imx8qxp-mek and create overlay file to enable
it because it can work at two mode: MIPI and parallel mode.

Signed-off-by: Frank Li <Frank.Li@xxxxxxx>
---
change in v2
- move ov5640 part to overlay file
- rename to imx8qxp-mek-ov5640-parallel.dtso
- remove data-lanes
