Philipp Tomsich 49cd8e85eb rockchip: efuse: add (misc) driver for RK3399 non-secure efuse block
This adds a simple driver for reading the efuse block of the RK3399.
It should be easy enough to add drivers for other devices (e.g. the
RK3328, RK3368, etc.) by passing the device details via driver_data.

Unlike the kernel driver (using the nvmem subsystem), we don't expose
the efuse as multiple named cells, but rather as a linear memory that
can be read using misc_read(...).

The primary use case (as of today) is the generation of a 'serial#'
(and a 'cpuid#') environment variable for the RK3399-Q7 (Puma)
system-on-module.

Note that this adds a debug-only (i.e. only if DEBUG is defined)
command 'rk3399_dump_efuses' that dumps the efuse block's content.
N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to
      include a SoC-name (together with a comment in the function) to
      remind whoever adds support for additional SoCs that this
      function currently makes assumptions regarding the size of the
      fuse-box based on the RK3399. The hope is that the function is
      adjusted to reflect any changes resulting from generalising the
      driver for multiple SoCs and is then renamed.
