arm64: dts: qcom: ipq8074: fix Gen3 PCIe node

[ Upstream commit 3e83a9c41ab0244a45a4a2800b9adb8de0d15f82 ]

IPQ8074 comes in 2 silicon versions:
* v1 with 2x Gen2 PCIe ports and QMP PHY-s
* v2 with 1x Gen3 and 1x Gen2 PCIe ports and QMP PHY-s

v2 is the final and production version that is actually supported by the
kernel, however it looks like PCIe related nodes were added for the v1 SoC.

Finish the PCIe fixup by using the correct compatible, adding missing ATU
register space, declaring max-link-speed, use correct ranges, add missing
clocks and resets.
