Jonas Blixt 9a1fe8d689 watchdog: imx_sc_wdt: Don't disable WDT in suspend
[ Upstream commit 2d9d6d300fb0a4ae4431bb308027ac9385746d42 ]

Parts of the suspend and resume chain is left unprotected if we disable
the WDT here.

>From experiments we can see that the SCU disables and re-enables the WDT
when we enter and leave suspend to ram. By not touching the WDT here we
are protected by the WDT all the way to the SCU.

README

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.
