[PATCH 04/41] dt-bindings: phy: migrate QMP PCIe PHY bindings to qcom,sc8280xp-qmp-pcie-phy.yaml

Migrate legacy bindings (described in qcom,ipq8074-qmp-pcie-phy.yaml)
to qcom,sc8280xp-qmp-pcie-phy.yaml. This removes a need to declare
the child PHY node or split resource regions.

-title: Qualcomm QMP PHY controller (PCIe, IPQ8074)
-
-maintainers:
-  - Vinod Koul <vkoul at kernel.org>
-
-description:
-  QMP PHY controller supports physical layer functionality for a number of
-  controllers on Qualcomm chipsets, such as, PCIe, UFS, and USB.
-
-  Note that these bindings are for SoCs up to SC8180X. For newer SoCs, see
-  qcom,sc8280xp-qmp-pcie-phy.yaml.
