[PATCH] dt-bindings: PCI: qcom: Allow 'vddpe-3v3-supply' again

[Johan Hovold <johan+linaro@kernel.org>]

Commit 756485bfbb85 ("dt-bindings: PCI: qcom,pcie-sc7280: Move SC7280 to
dedicated schema") incorrectly removed 'vddpe-3v3-supply' from the
bindings, which results in DT checker warnings like:

	arch/arm64/boot/dts/qcom/msm8996-sony-xperia-tone-dora.dtb: pcie@600000: Unevaluated properties are not allowed ('vddpe-3v3-supply' was unexpected)
        from schema $id: http://devicetree.org/schemas/pci/qcom,pcie.yaml#

Note that this property has been part of the Qualcomm PCIe bindings
since 2018 and would need to be deprecated rather than simply removed if
there is a desire to replace it with 'vpcie3v3' which is used for some
non-Qualcomm controllers.
