[PATCH v7 5/7] dt-bindings: PCI: qcom: Document the IPQ5332 PCIe controller

[Varadarajan Narayanan <quic_varada@quicinc.com>]

Document the PCIe controller on IPQ5332 platform. IPQ5332 will
use IPQ9574 as the fall back compatible.

Signed-off-by: Varadarajan Narayanan <quic_varada@quicinc.com>
---
v7: Moved ipq9574 related changes to a separate patch
    Add 'global' interrupt

v6: Commit message update only. Add info regarding the moving of
    ipq9574 from 5 "reg" definition to 5 or 6 reg definition.

v5: Re-arrange 5332 and 9574 compatibles to handle fallback usage in dts

v4: * v3 reused ipq9574 bindings for ipq5332. Instead add one for ipq5332
    * DTS uses ipq9574 compatible as fallback. Hence move ipq9574 to be able
      to use the 'reg' section for both ipq5332 and ipq9574. Else, dtbs_check
      and dt_binding_check flag errors.
