Subject: [PATCH v8 06/15] dt-bindings: rtc: Add fsl,scu-rtc yaml file

From: Abel Vesa <abel.vesa@....com>

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'rtc' child node of the SCU main node.
