Subject: [PATCH v3 01/15] dt-bindings: PCI: qcom: Fix sc8180x clocks and interrupts

Commit 45a3ec891370 ("PCI: qcom: Add sc8180x compatible") added sc8180x
compatible and commit 075a9d55932e ("dt-bindings: PCI: qcom: Convert to
YAML") converted the description to yaml

But there are still some errors specific to sc8180x which this change
attempts to fix. The clocks and resets for sc8180 pcie controller are
different so need to be documented separately
