Previous patch intends to restore the flash's QE bit when removed/shutdown,
but may have some problems and break the flash:
- for those originally in Quad mode, this patch will clear the QE bit
when unloaded the flash, which is incorrect.
- even with above problem solved, it may still break the flash as some
flash's QE bit is non-volatile and lots of set/reset will wear out
the bit.
- the restore method cannot be proved to be valid as if a hard
reset or accident crash happened, the spi_nor_restore() won't be
performed the the QE bit will not be restored as we expected to.
So let's revert it to fix this. The discussion can be found at [1].

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.
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.
