arm64: dts: sm8650: Add msi-map-mask for PCIe nodes

"msi-map-mask" is a required property for all Qcom PCIe controllers as it
would allow all PCIe devices under a bus to share the same MSI identifier.

Without this property, each device has to use a separate MSI identifier
which is not possible due to platform limitations.

Currently, this is not an issue since only one device is connected to the
bus on boards making use of this SoC.
