Amlogic Meson8 and Meson8b SRAM for smp bringup:

Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.
Once the core gets powered up it executes the code that is residing at a
specific location.

Therefore a reserved section sub-node has to be added to the mmio-sram

Required sub-node properties:
- compatible : depending on the SoC this should be one of:

The rest of the properties should follow the generic mmio-sram discription
found in ../../misc/sram.txt


	sram: sram@d9000000 {
		compatible = "mmio-sram";
		reg = <0xd9000000 0x20000>;
		#address-cells = <1>;
		#size-cells = <1>;
		ranges = <0 0xd9000000 0x20000>;

		smp-sram@1ff80 {
			compatible = "amlogic,meson8b-smp-sram";
			reg = <0x1ff80 0x8>;
