Subject: [PATCH] dt-bindings: fsl: fsl,rcpm: fix unevaluated fsl,rcpm-wakeup property

Drop the RCPM consumer example from the binding (LPUART device node),
because:
1. Using phandles is typical syntax, thus explaining it is not needed in
   the provider binding,
2. It has 'fsl,rcpm-wakeup' property which is not allowed by LPUART
   binding so it causes dt_binding_check warning:

   fsl,rcpm.example.dtb: serial@...0000: Unevaluated properties are not allowed ('fsl,rcpm-wakeup' was unexpected)
     from schema $id: http://devicetree.org/schemas/serial/fsl-lpuart.yaml#

Alternatively, this property could be added to LPUART binding
(fsl-lpuart.yaml), but it looks like none of in-tree DTS use it.
