At runtime_resume(), read the W1 (Wrapper Register 1) register to detect if an hardware reset occurred. If it did, run the hardware init sequence. This callback will be called at system-wide resume. Previously, if a reset occurred during suspend, we would crash. The wrapper config had not been written, leading to invalid register accesses inside cdns3.

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.
