[PATCH v3 6/8] ARM: dts: sun8i: Add Reduced Serial Bus controller device node to A23/A33 dtsi

[Chen-Yu Tsai <wens-jdAy2FN1RRM@public.gmane.org>]

This patch adds a device node for the Reduced Serial Bus (RSB)
controller and the defacto pinmux setting to the A23/A33 dtsi.

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