This series adds support for the StarFive JH7100 SoC to the SiFive cache
controller driver. The JH7100 was a "development version" of the JH7110
used on the BeagleV Starlight and VisionFive V1 boards. It has
non-coherent peripheral DMAs but was designed before the standard RISC-V
Zicbom extension, so it neeeds support in this driver for non-standard
cache management.

Since v1:
- Fix email threading, hopefully.
- Drop sifive,ccache-ops device tree property and just match on the
  compatible. (Conor)

I'll grab these after the mw, presuming nothing comes up in the interim.

Applied to riscv-cache-for-next, thanks! I still need to figure out how
I want to put things into linux-next as Arnd wants these cache driver
things in a PR of their own.
