The pmu-sram is used to store resume code, suspend/resume need get the
address of it. Therefore add a node and documentation for it.

This patch just adds bindings, not a node.

Title of this patch should probably mention bindings somewhere.  Also
bindings should be patch #3 and the adding to the DTS patch #4.

+Rockchip SRAM for pmu:
+------------------------------
+
+The sram of pmu is used to store the function of resume from maskrom(the 1st
+level loader).
+
+Required node properties:
+- compatible : should be "rockchip,rk3288-pmu-sram"
+- reg : physical base address and the size of the registers window
+
+Example:
+	pmu_intmem@ff720000 {
+		compatible = "mmio-sram", "rockchip,rk3288-pmu-sram";
+		reg = <0xff720000 0x4000>;
+	};
