Split layerscape-pci.txt into two yaml files: fsl,layerscape-pcie-ep.yaml
and fsl,layerscape-pcie.yaml.
yaml files contain the same content as the original txt file.
The subsequent commit will fix DTB_CHECK failure.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Please omit these errors. Bjorn require create a identical version as

Origial txt will cause DTB_CHECK error. The problem will be fixed at next

One of these is a real error - caused by a typo. "dma-coherence" should
be "dma-coherent".
