On ipq9574, there are 4 PCIe controllers. Describe the pcie2 and pcie3
nodes, and their PHYs in devicetree.

The pcie0 and pcie1 controllers use a gen3x1 PHY, which is not
currently supported. Hence, only pcie2 and pcie3 are described. Only
pcie2 was tested because my devboard only has conenctions to pcie2.

There is a mistake here with the clock-names :( . Will fix it in v5.
