Implement the ->restore() PM operation and set the link to off, which will force a full reset and restore. This ensures that Host Performance Booster is reset after suspend-to-disk. The Host Performance Booster feature caches logical-to-physical mapping information in the host memory. After suspend-to-disk, such information is not valid, so a full reset and restore is needed. A full reset and restore is done if the SPM level is 5 or 6, but not for other SPM levels, so this change fixes those cases. A full reset and restore also restores base address registers, so that code is removed.

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.
