Currently there is a single notification chain which is called whenever any remoteproc shuts down. This leads to all the listeners being notified, and is not an optimal design as kernel drivers might only be interested in listening to notifications from a particular remoteproc. Create a global list of remoteproc notification info data structures. This will hold the name and notifier_list information for a particular remoteproc. The API to register for notifications will use name argument to retrieve the notification info data structure and the notifier block will be added to that data structure's notification chain. Also move from blocking notifier to srcu notifer based implementation to support dynamic notifier head creation.

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.
