MLK-24494-5: arm64: dts: imx8mp: add dts for ov2775 and ov5640 support

Add dts for OV2775 + OV5640 for iMX865-EVK board. OV2775 connect to
CSI port 0 and OV5640 connect to CSI port 1, as bellow:
   OV2775 => CSI1
   OV5640 => CSI2
Board need to rework to support this feature. More info, please
refer to rework guide provided by NXP
