[PATCH v4 RESEND 3/8] dt-bindings: PCI: qcom: Add IPQ9574 PCIe controller

IPQ9574 has PCIe controllers which are almost identical to IPQ6018.
The difference is that the "iface" clock is replaced by the "snoc",
and "anoc". The "sleep" reset is replaced by an "aux" reset.
Document these differences along with the compatible string.
