[PATCH 09/21] arm64: dts: qcom: sc8280xp: Add PCIe bridge node

From: Manivannan Sadhasivam
Date: Tue Feb 20 2024 - 22:46:54 EST


On Qcom SoCs, the PCIe host bridge is connected to a single PCIe bridge
for each controller instance. Hence, add a node to represent the bridge.

While at it, let's remove the bridge properties from board dts as they are
now redundant.
