dt-bindings: riscv: microchip: document icicle reference design
The icicle kit reference design's v2022.09 release made some changes to the memory map - including adding the ability to read the fabric clock controllers via the system controller bus & making the PCI controller work with upstream Linux. While the PCI was not working in the v2022.03 design, so nothing is broken there in terms of backwards compatibility, the fabric clocks used in the v2022.03 design were chosen by the individual run of the synthesis tool. In the v2022.09 reference design, the clocks are fixed to use the "north west" fabric Clock Conditioning Circuitry. In the v2022.10 release, the memory map on the DDR side is also changing, so to avoid making a breaking change here twice, jump over the v2022.09 release and straight to the v2022.10 one. Make use of a new compatible to denote that v2022.{09,10} reference design releases are not backwards compatible.
