In the NVM Express Revision 1.4 spec, Figure 145 describes possible values for an AER with event type "Error" (value 000b). For a Persistent Internal Error (value 03h), the host should perform a controller reset. Add support for this error using code that already exists for doing a controller reset. As part of this support, introduce two utility functions for parsing the AER type and subtype. This new support was tested in a lab environment where we can generate the persistent internal error on demand, and observe both the Linux side and NVMe controller side to see that the controller reset has been done.

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.
