[PATCH 01/12] dt-bindings: riscv: sifive-ccache: Add compatible for StarFive JH7100 SoC

[Cristian Ciocaltea <cristian.ciocaltea@collabora.com>]

Document the compatible for the SiFive Composable Cache Controller found
on the StarFive JH7100 SoC.

This also requires extending the 'reg' property to handle distinct
ranges, as specified via 'reg-names'.
