[PATCH v4 09/13] ARM: dts: sun8i-a83t: Add RSB controller device node to dtsi

[Vishnu Patekar <vishnupatekar0510@gmail.com>]

This patch adds a device node for the Reduced Serial Bus (RSB)
controller and the defacto pinmux setting to the A83T dtsi.

Since there is only one possible pinmux setting for RSB, just
set it in the dtsi.
