[ Upstream commit 5d3d966400d0a094359009147d742b3926a2ea53 ]
For historical reasons on SM8450 the second PCIe host (pcie1) also keeps
a reference to the PIPE clock coming from the PHY. Commit e76862840660
("arm64: dts: qcom: sm8450: correct pcie1 phy clocks inputs to gcc") has
updated the PHY to use #clock-cells = <1>, making just <&pcie1_phy>
clock specification invalid. Update corresponding clock entry in the
PCIe1 host node.
/soc@0/pcie@1c08000: Failed to get clk index: 2 ret: -22
qcom-pcie 1c08000.pcie: Failed to get clocks
qcom-pcie 1c08000.pcie: probe with driver qcom-pcie failed with error -22
