[PATCH 1/3] ARM: dts: sunxi: Add syscon node for controlling SRAM mapping

[Jens Kuske <jenskuske-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Chen-Yu Tsai <wens-jdAy2FN1RRM@public.gmane.org>

Allwinner SoCs have a system controller module that controls whether
SRAM blocks are mapped to the CPU memory or specific peripherals.
