Subject: [PATCH 03/10] dt-bindings: PCI: qcom: Enumerate platforms with single msi interrupt

Explicitly enumerate the older platforms that have a single msi host
interrupt. This allows for adding further platforms without resorting
to nested conditionals.

Drop the redundant comment about older chipsets instead of moving it.
