[PATCH v1 1/4] nvmem: rockchip-efuse: update compatible strings for Rockchip efuse

From: Finley Xiao <finley.xiao at rock-chips.com>

Rk3399-efuse is organized as 32bits by 32 one-time programmable
electrical fuses. The efuse of earlier SoCs are organized as
32bits by 8 one-time programmable electrical fuses with random
access interface.

Add different device tree compatible string for different SoCs
to be able to differentiate between the two.
