[PATCH] dt-bindings: clock: imx5: fix example

[Marc Kleine-Budde]

Since commit:

    0e030a373df3 ("can: flexcan: fix endianess detection")

the fsl,imx53-flexcan isn't compatible with the fsl,p1010-flexcan any more. As
the former accesses the IP core in Little Endian mode and the latter uses Big
Endian mode.

With the conversion of the flexcan DT bindings to yaml, the dt_binding_check
this throws the following error:

Documentation/devicetree/bindings/clock/imx5-clock.example.dt.yaml: can@53fc8000: compatible: 'oneOf' conditional failed, one must be fixed:
        ['fsl,imx53-flexcan', 'fsl,imx25-flexcan'] is too long
        Additional items are not allowed ('fsl,imx25-flexcan' was unexpected)
        'fsl,imx53-flexcan' is not one of ['fsl,imx7d-flexcan', 'fsl,imx6ul-flexcan', 'fsl,imx6sx-flexcan']
        'fsl,imx53-flexcan' is not one of ['fsl,ls1028ar1-flexcan']
        'fsl,imx6q-flexcan' was expected
        'fsl,lx2160ar1-flexcan' was expected
        From schema: Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml

The error is fixed by removing the "fsl,p1010-flexcan" compatible (which turned
out the be incompatible) from the binding example.

But you just added that "fsl,imx53-flexcan" has a fallback of 
'fsl,imx25-flexcan'. 

Looks like "fsl,imx53-flexcan" alone needs to be dropped. Decide the one 
way that is valid please. I've dropped the schema change until sorted 
out.

I've fixed things up with this and the compatible fixes and applied as 
this needs to get into rc4.
