Subject: [PATCH 7/9] riscv: dts: microchip: icicle: re-jig fabric peripheral addresses

When users try to add onto the reference design, they find that the
current addresses that peripherals connected to Fabric InterConnect
(FIC) 3 use are restrictive. For the v2022.09 reference design, the
peripherals have been shifted down, leaving more contiguous address
space for their custom IP/peripherals.
