[v4,00/10] qcom: add support for PCIe0 on SM8450 platform

Message

There are two different PCIe controllers and PHYs on SM8450, one having
one lane and another with two lanes. This set of patches adds support
for the first PCIe phy and controller only, support for the second PCIe
part will come later.

Changes since v3:
 - Fix pcie gpios to follow defined schema as noted by Rob
 - Fix commit message according to Bjorn's suggestions

Changes since v2:
 - Remove unnecessary comment in struct qcom_pcie_cfg

Changes since v1:
 - Fix capitalization/wording of PCI patch subjects
 - Add missing gen3x1 specification to PHY table names
