[PATCH 0/4] Add CCI support for Milos, enable on Fairphone (Gen. 6)

Add the compatible strings for the CCI busses on Milos, and the EEPROMs
found on the Fairphone (Gen. 6) camera modules, and add them to the
milos dtsi and device dts.

This series soft-depends on https://lore.kernel.org/linux-arm-msm/20260116-milos-camcc-icc-v1-0-400b7fcd156a@fairphone.com/T/

The patches can be applied without the dependency, but the final dts
patches should probably only land once the other series has been fully
applied, otherwise the CCI busses cannot actually be used (unless some
other component turns on the mmss_noc) and you get a kernel warning like
the following:
