PCI: qcom: Add support for SA8540P
The SA8540P platform has five PCIe controllers: two 4-lane, two 2-lane
and one 1-lane.
Add a new "qcom,pcie-sa8540p" compatible string and reuse the 1.9.0 ops.
Note that like for SC8280XP, the SA8540P controllers need two or three
interconnect clocks to be enabled.
