Subject: [PATCH 07/11] dt-bindings: PCI: qcom-ep: Make PERST separation optional

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.
