Subject: [PATCH v6] dt-bindings: imx-pata: Convert to dtschema

This patchset converts imx-pata bindings to DT schema.
file name is changed to fsl,imx-pata to follow vendor,device scheme
imx31-pata and imx51-pata are added in compatible to ensure this node compiles to
imx31-pata.dtsi or imx51-pata.dtsi
oneOf is also added to allow the usage of imx27 alone.
Cleanups are done in patch 6

Signed-off-by: Animesh Agarwal <animeshagarwal28@...il.com>

Changes in v6:
- removed items before const due to single element.

Changes in v5:
- added oneOf in compatible property to allow the usage of imx27 alone.

Changes in v4:
- added fsl,imx31-pata in compatible property as enum
- imx31-pata was not listed in compatible in original txt binding
- adding imx31-pata in enum ensures the node compiles to imx31.dtsi

Changes in v3:
- added fsl,imx51-pata in compatible property as enum
- imx51-pata was not listed in compatible in original txt binding
- adding imx51-pata in enum ensures the node compiles to imx31.dtsi
- fsl,imx27-pata is added as a const to ensure it is present always

Changes in v2:
- fixed style issues
- compatible property now matches the examples
- fixed yamllint warnings/errors
