[PATCH] arm64: dts: rockchip: Add CSI-2 bus type to ROCK 5B+ camera overlays

[Fabio Estevam]

The Rockchip RK3568 MIPI CSI-2 receiver binding requires the bus-type
property in its input endpoint.

Specify that the Radxa CAM4K modules connected to CSI2 and CSI4 use a
MIPI CSI-2 D-PHY bus. This fixes the following dtbs_check warning:

endpoint: 'bus-type' is a required property
