The Amlogic SRAM bindings list only compatible so integrate them into
generic SRAM bindings schema.

-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
-declaration.
-
-Required sub-node properties:
-- compatible : depending on the SoC this should be one of:
-		"amlogic,meson8-smp-sram"
-		"amlogic,meson8b-smp-sram"
-
-The rest of the properties should follow the generic mmio-sram discription
-found in ../../misc/sram.txt
-
-Example:
-
-	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>;
-		};
-	};
