PERST separation is an optional debug feature used to collect the crash dump from the PCIe endpoint devices by the PCIe host when the endpoint crashes. This feature keeps the PCIe link up by separating the PCIe IP block from the SoC reset logic. So remove the corresponding property "qcom,perst-regs" from the required properties list.
