Subject: [PATCH V7 2/4] arm64: dts: qcom: ipq9574: Add PCIe PHYs and controller nodes

From: devi priya <quic_devipriy@...cinc.com>

Add PCIe0, PCIe1, PCIe2, PCIe3 (and corresponding PHY) devices
found on IPQ9574 platform. The PCIe0 & PCIe1 are 1-lane Gen3
host whereas PCIe2 & PCIe3 are 2-lane Gen3 host.
