Currently SCMI VirtIO channels are marked with a ready flag and related lock to track channel lifetime and support proper synchronization at shutdown when virtqueues have to be stopped. This leads to some extended spinlocked sections with IRQs off on the RX path to keep hold of the ready flag and does not scale well especially when SCMI VirtIO polling mode will be introduced. Add an SCMI VirtIO channel dedicated refcount to track active users on both the TX and the RX path and properly enforce synchronization and cleanup at shutdown, inhibiting further usage of the channel once freed.

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.
