commit 622007d172fbb1d7556329bafd72dc28c0baf1b8 upstream.

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.
