[PATCH v3 1/4] dt-bindings: PCI: pci-imx6: Fix build warning after adding extref clock

[Richard Zhu <hongxing.zhu@nxp.com>]

Fix dtbs_check build warnings by updating the maxItems property for
clocks in fsl,imx6q-pcie-common.yaml and completing the clock
descriptions in fsl,imx6q-pcie.yaml.

The warnings occur because the clock arrays exceed the previously
defined maximum length:

imx943-evk.dtb: pcie@4c380000 (fsl,imx95-pcie): clock-names: ['pcie', 'pcie_bus', 'pcie_phy', 'pcie_aux', 'ref', 'extref'] is too long
imx943-evk.dtb: pcie@4c300000 (fsl,imx95-pcie): clocks: [[5, 74], [5, 41], [5, 40], [5, 75], [46, 0], [47]] is too long

Fixes: 1352f58d7c8d ("dt-bindings: PCI: pci-imx6: Add external reference clock input")
