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

[Jianqun Xu <jay.xu@rock-chips.com>]

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.
