commit 8cdb8f1ab7efbd88868d3067ec1f211ff289bc01 upstream.

Describe SCIF ports in the R8A77470 device tree.
Also it fixes the CPG clock index ZS from 6 to 5.

[fab: reworked to make it fit 4.4.y-cip definitions, like include
files, and properties like clocks, clock-names, and power-domains.
Also, removed resets properties as not applicable here. Finally,
the fix for the ZS clock index is not applicable to this version]
