Subject: [PATCH v3 5/8] riscv: dts: microchip: make the fabric dtsi board specific

From: Conor Dooley <conor.dooley@...rochip.com>

Currently mpfs-fabric.dtsi is included by mpfs.dtsi - which is fine
currently since there is only one board with this SoC upstream.

However if another board was added, it would include the fabric contents
of the Icicle Kit's reference design. To avoid this, rename
mpfs-fabric.dtsi to mpfs-icicle-kit-fabric.dtsi & include it in the dts
rather than mpfs.dtsi.
