From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
Add PCIe support for Qcom SM8250 SoC. This SoC has 3 PCIe Gen 3
instances based on Designware IP, out of which PCIe0 has 1 lane support
and the rest have 2 lane support.

From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
RB5 has 3 PCIe ports exposed to connect PCIe client devices. PCIe0 is
connected to QCA6391 chipset and others are available on the HS3
expansion connector. Hence, enable all of them.
