[PATCH/RFC 04/11] ARM: shmobile: r8a7793 dtsi: Add device node for RST module

[Geert Uytterhoeven]

Add a device node for the RST module, which provides reset control.
Declare it to be a system controller (syscon), so other device nodes can
refer to its registers.

TODO Add DT binding documentation.
