riscv: dts: microchip: add the mpfs' fabric clock control
The "fabric clocks" in current PolarFire SoC device trees are not really fixed clocks. Their frequency is set by the bitstream, so having them located in -fabric.dtsi is not a problem - they're just as "fixed" as the IP blocks etc used in the FPGA fabric. However, their configuration can be read at runtime (and to an extent they can be controlled, although the intended usage is static configurations set by the bitstream) through the system controller bus.
In the v2022.09 icicle kit reference design a single CCC (north-west corner) is enabled, using a 50 MHz off-chip oscillator as its reference.
Updating to the v2022.09 icicle kit reference design is required, as prior to this release, the CCC was not fixed & could change for any given run of the synthesis tool.

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.

riscv: dts: microchip: icicle: update pci address properties
For the v2022.09 reference design the PCI root port's data region has been moved to FIC1 from FIC0. This is a shorter path, allowing for higher clock rates and improved through-put. As a result, the address at which the PCIe's data region appears to the core complex has changed. The config region's address is unchanged.
As FIC0 is no longer used, its clock can be removed too.

riscv: dts: microchip: move the mpfs' pci node to -fabric.dtsi
In today's edition of moving things around:
The PCIe root port on PolarFire SoC is more part of the FPGA than of the Core Complex. It is located on the other side of the chip and, apart from its interrupts, most of its configuration is determined by the FPGA bitstream rather. This includes:
- address translation in both directions - the addresses at which the config and data regions appear to the core complex - the clocks used by the AXI bus - the plic interrupt used
Moving the PCIe node to the -fabric.dtsi makes it clearer than a singular configuration for root port is not correct & allows the base SoC dtsi to be more easily included.

riscv: dts: microchip: add pci dma ranges for the icicle kit
The recently removed, accidentally included, "matr0" property was used in place of a dma-ranges property. The PCI controller is non-functional with mainline Linux in the v2022.02 or later reference designs and has not worked without configuration of address-translation since v2021.08.
Add the address translation that will be used by the v2022.09 reference design & update the compatible used by the dts. Since this change is not backwards compatible, update the compatible to denote this, jumping over v2022.09 directly to v2022.10.

riscv: dts: microchip: make the fabric dtsi board specific
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.
mpfs-icicle-kit-fabric.dtsi specifically matches the 22.03 reference design for the icicle kit's FPGA fabric & an older version of the design may not have the i2c or pwm devices - so add the compatible string to document this.
