dt-bindings: PCI: qcom,pcie-sc7280: Update bindings adding eight interrupts

Previous commit to this bindings, commit 756485bf ("dt-bindings:
PCI: qcom,pcie-sc7280: Move SC7280 to dedicated schema"), updated the
bindings to specify one interrupt only, as the devicetree at that time
did not describe the hardware fully.

The devicetree for SC7280 now specifies eight interrupts, following the
commit b8ba66b4 ("arm64: dts: qcom: sc7280: Add additional MSI
interrupts").

Thus, update the bindings to reflect this.
