Subject: [PATCH v3 2/4] dt-bindings: PCI: qcom: correct clocks for SC8180x

PCI node in Qualcomm SC8180x DTS has 8 clocks:

  sc8180x-primus.dtb: pci@...0000: 'oneOf' conditional failed, one must be fixed:
    ['pipe', 'aux', 'cfg', 'bus_master', 'bus_slave', 'slave_q2a', 'ref', 'tbu'] is too short

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

Please take the patch via PCI tree.

Changes in v3:
1. Split from sm8150 change. Due to split/changes around sm8150, drop
   Mani's Rb tag.
2. Drop unneeded oneOf for clocks.

Changes in v2:
1. Add Acs/Rb.
2. Correct error message for sm8150.
