IPQ8074 has two PCIe ports both are based on synopsis designware PCIe
controller. while it was assumed that PCIe support for IPQ8074 was already
available. PCIe was not functional until now.

This patch series adds support for PCIe ports on IPQ8074.

First PCIe port is of gen2 synposis version is 2_3_2 which has already been
enabled. But it had some problems on phy init and needed dt updates.

Second PCIe port is gen3 synopsis version is 2_9_0. This series adds
support for this PCIe port while fixing dt nodes.

Patch 1 on this series depends on qcom pcie bindings patch
