Subject: [PATCH 1/2] rockchip: efuse: add documentation for rk3288 efuse driver

In RK3288, there are two eFuse. One is organized as 32bits by 8 one-time programmable
electrical fuses with random access interface, and the other is organized as 32bits by 32
one-time programmable electrical fuses.
The 32x32 eFuse can only be accessed by APB bus when IO_SECURITYsel is high.

+ROCKCHIP RK3288 efuse block.
+
+Required properties:
+- compatible : should be:

+- reg: Should contain 1 entry: the entry gives the physical address and length
+       of the fuse registers.
+
+Example:
+
+	efuse: efuse@...40000 {
+		compatible = "rockchip,rk3288-efuse";
