Add the camera subsystem (CAMSS) node for the Nord SoC and enable it on
the Nord RRD and Nord Ride Embedded boards.

Dependencies:
- Nord CAMSS: https://lore.kernel.org/all/20260915-nord-v1-0-20db41a7f1ff@oss.qualcomm.com/
- Clock DTS: https://lore.kernel.org/all/20260920081049.2183845-1-shengchao.guo@oss.qualcomm.com/
- Ride Embedded DTS: https://lore.kernel.org/all/20260920084920.2201418-1-shengchao.guo@oss.qualcomm.com/

Add the camera subsystem node for the Nord SoC with its 5 CSIPHY, 3 CSID
plus 10 CSID lite and 3 IFE plus 10 IFE lite blocks, along with their
clocks, interrupts, interconnects, SMMU stream IDs and power domains.
