Conor Dooley 2b55915d27 riscv: dts: microchip: mpfs: remove bogus card-detect-delay ...

Recent versions of dt-schema warn about a previously undetected
undocumented property:
arch/riscv/boot/dts/microchip/mpfs-icicle-kit.dtb: mmc@20008000: Unevaluated properties are not allowed ('card-detect-delay' was unexpected)
        From schema: Documentation/devicetree/bindings/mmc/cdns,sdhci.yaml

There are no GPIOs connected to MSSIO6B4 pin K3 so adding the common
cd-debounce-delay-ms property makes no sense. The Cadence IP has a
register that sets the card detect delay as "DP * tclk". On MPFS, this
clock frequency is not configurable (it must be 200 MHz) & the FPGA
comes out of reset with this register already set.
