02baff3254 nvmem: rockchip-efuse: add rk3399-efuse support
1) the efuse timing of rk3399 is different from earlier SoCs.
2) rk3399-efuse is organized as 32bits by 32 one-time programmable
electrical fuses, the efuse of earlier SoCs is organized as 32bits
by 8 one-time programmable electrical fuses with random access interface.

This patch adds a new read function for rk3399-efuse.

This patch moves to nvmem support in the driver to use callback
instead of regmap.

c37ff3fbe0 nvmem: rockchip: trivial: Make the driver more readability
1) Make the include file to sort from order
2) clean up the driver to make more readability

Let's clean up such trivial details.

03a69568e0 nvmem: Adding bindings for rockchip-efuse
There are some SoC specified values store in eFuse,
such as the cpu_leakage and cpu_version,
this driver can expose these values to /sys base on nvmem.
