This reverts commit 15a3adfe75937c9e4e0e48f0ed40dd39a0e526e2.
The backport of [1] relies on having [2] also backported. Having only
one of the two results in a bogus hw->timing1 setting.
If only [2] is backportet the 16 bit register value likely underflows
resulting in a busy_wait_timeout of 0.
Or if only [1] is applied the value likely overflows with chances of
having last 16 LSBs all 0 which would then result in a
busy_wait_timeout of 0 too.
Both cases may lead to NAND data corruption, e.g. on a Colibri iMX7
setup this has been seen.

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.
