[PATCH 1/6] dt-bindings: perf: fsl-imx-ddr: Add compatible string for i.MX8QM, i.MX8QXP and i.MX8DXL

[Frank Li]

Add compatible string fsl,imx8qm-ddr-pmu, fsl,imx8qxp-ddr-pmu and
fsl,imx8dxl-db-pmu (for data bus fabric).

Add clocks and clock-names for fsl,imx8dxl-db-pmu and keep the same
restriction for existing compatible strings.
