dt-bindings: PCI: qcom,pcie-sm8550: Add Eliza compatible

PCIe controller present in Eliza SoC is backwards compatible with the
controller present in SM8550 SoC. Hence, add the compatible with SM8550
fallback.

Eliza requires 6 reg entries, 8 clocks and 9 interrupts, so add the
corresponding allOf constraints.
