[PATCH 3/4] dt-bindings: PCI: microchip,pcie-host: fix incorrect child node name

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

v2022.08 of dt-schema improved checking of unevaluatedProperties, and
exposed a previously unseen warning for the PCIe controller's interrupt
controller node name:

arch/riscv/boot/dts/microchip/mpfs-icicle-kit.dtb: pcie at 2000000000: Unevaluated properties are not allowed ('clock-names', 'clocks', 'legacy-interrupt-controller', 'microchip,axi-m-atr0' were unexpected)
        From schema: Documentation/devicetree/bindings/pci/microchip,pcie-host.yaml

Make the property in the binding match the node name actually used in
the dts.

Fixes: dcd49679fb3a ("dt-bindings: PCI: Fix 'unevaluatedProperties' warnings")

This is another one Rob where I feel like I'm doing the wrong thing.
The Linux driver gets the child node without using the name, but
another OS etc could in theory (or reality), right?
