Finley Xiao 30c2580e53 nvmem: rockchip-efuse: Add mutex lock for rk1808 efuse read 
The rk1808 efuse read has some issues when several threads start to read
efuse through nvmem file node.

Thread1                                    thread2
1. timing_init
2.  write auto_ctrl
3.    delay                                  timing_init
4.      read status                            write auto_ctrl
5.        if error goto to timing_deinit         delay

The thread1 will read no finish bit and then goto error, the user will
see a "Input/Output Error".

The thread1 do timing deinit will cause thread2 halt on read status, and
the user will never success to do read efuse again.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
