ARM: dts: sun4i: Add A10 SRAM and SRAM controller

Browse Source 
The A10 has a few SRAM that can be mapped either to a device or to the CPU,
with the mapping being controlled by a SRAM controller.

Add the SRAM controller, the SRAM that it drives and the section that can
be used by the various devices.
