Subject: [PATCH v2 1/4] arm64: dts: renesas: aistarvision-mipi-adapter-2.1: Add parent macro for each sensor

For HiHope RZ/G2H the OV5645 sensor is populated on i2c2 whereas the imx219
sensor is populated on i2c3 so add support for handling such cases by
adding a parent macro for each sensor.

Also update r8a774c0-ek874-mipi-2.1.dts to incorporate the changes.
