David Lazar 3bde7ec13c platform/x86: Add s2idle quirk for more Lenovo laptops 
When suspending to idle and resuming on some Lenovo laptops using the
Mendocino APU, multiple NVME IOMMU page faults occur, showing up in
dmesg as repeated errors:

nvme 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000b
address=0xb6674000 flags=0x0000]

The system is unstable afterwards.

Applying the s2idle quirk introduced by commit 455cd867b8 ("platform/x86:
thinkpad_acpi: Add a s2idle resume quirk for a number of laptops")
allows these systems to work with the IOMMU enabled and s2idle
resume to work.

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.
