Add implementation to allow forcing all camera buffer allocations to be CACHED and mapped as CACHED while iommu_map. This is enabled based on DT property. Force this only if io-coherency is enabled. Validations are added to make sure a correct combination of "force_cache" and "io-coherency" properties are mentioned in DT.
