[PATCH v2 1/3] dt-bindings: PCI: imx6q-pcie: Add intr, aer and pme interrupts

[Hongxing Zhu]

Hi Frank:
I didn't include your "Reviewed-by: Frank Li Frank.Li at nxp.com" tag in the v2
patch-set because there were some changes made in v2. If you don't mind, I
would add your reviewed-by tag in the next version (v3) if you don't have
suggestions on the changes.

Best Regards
Richard Zhu
