dt-bindings: PCI: fsl,imx6q: fix assigned-clocks warning

assigned-clocks are a dependency of clocks, however the dtschema has
limitation and expects clocks to be present in the binding using
assigned-clocks, not in other referenced bindings. The clocks were
defined in common fsl,imx6q-pcie-common.yaml, which is referenced by
fsl,imx6q-pcie-ep.yaml. The fsl,imx6q-pcie-ep.yaml used assigned-clocks
thus leading to warnings:

Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.example.dtb: pcie-ep@33800000:
Unevaluated properties are not allowed ('assigned-clock-parents', 'assigned-clock-rates', 'assigned-clocks' were unexpected)
From schema: Documentation/devicetree/bindings/pci/fsl,imx6q-pcie-ep.yaml

Fix this by moving clocks to each specific schema from the common one
and narrowing them to strictly match what is expected for given device.

Restruct i.MX PCIe schema, derive the common properties, thus they can
be shared by both the RC and Endpoint schema.

Update the description of fsl,imx6q-pcie.yaml, and move the EP mode
compatible to fsl,imx6q-pcie-ep.yaml.

Add support for i.MX8M PCIe Endpoint modes, and update the MAINTAINER
accordingly.
