Emmanuel Grumbach 50d1982dba wifi: iwlwifi: fix the check for the SCRATCH register upon resume
[ Upstream commit a17821321a ]

We can't rely on the SCRATCH register being 0 on platform that power
gate the NIC in S3. Even in those platforms, the SCRATCH register is
still returning 0x1010000.

Make sure that we understand that those platforms have powered off the
device.

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 reStructuredText 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.
