[PATCH v4 1/9] dt-bindings: PCI: fsl,imx6q: Add i.MX6Q and i.MX6QP PCIe EP compatibles

[Richard Zhu]

Add i.MX6Q and i.MX6QP PCIe EP compatibles.
- Make the interrupts property optional, since i.MX6Q/i.MX6QP PCIe
  don't have DMA capability.
- To pass the schema check, specify the clocks property refer to the
  different platforms.
