soc: sifive: ccache: Add StarFive JH7100 support
This adds support for the StarFive JH7100 SoC which also features this SiFive cache controller. The JH7100 has non-coherent DMAs but predate the standard RISC-V Zicbom exension, so instead we need to use this cache controller for non-standard cache management operations. Unfortunately the interrupt for uncorrected data is broken on the JH7100 and fires continuously, so add a quirk to not register a handler for it.
