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.

riscv: dts: microchip: reparent mpfs clocks
The 600M clock in the fabric is not the real reference, replace it with
a 125M clock which is the correct value for the icicle kit. Rename the
msspllclk node to mssrefclk since this is now the input to, not the
output of, the msspll clock. Control of the msspll clock has been moved
into the clock configurator, so add the register range for it to the clk
configurator. Finally, add a new output of the clock config block which
will provide the 1M reference clock for the MTIMER and the rtc.

From schema: dtschema/schemas/simple-bus.yaml
Fix this by moving the node out of the "soc" subnode.
While at it, rename it to "msspllclk", and drop the now superfluous
"clock-output-names" property.
Move the actual clock-frequency value to the board DTS, since it is not
set until bitstream programming time.

Devicetree source is a description of hardware and hardware has only one
block @20008000 which can be configured either as eMMC or SDHC. Having
two node for different modes is an obscure, unusual and confusing way to
configure it. Instead the board file is supposed to customize the block
to its needs, e.g. to SDHC mode.
