Subject: [PATCH v3 1/9] 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.

Make use of a new compatible to denote that this is not backwards
compatible.
