Introduce a new MEI client driver to support Late Binding firmware upload/update for Intel discrete graphics platforms. Late Binding is a runtime firmware upload/update mechanism that allows payloads, such as fan control and voltage regulator, to be securely delivered and applied without requiring SPI flash updates or system reboots. This driver enables the Xe graphics driver and other user-space tools to push such firmware blobs to the authentication firmware via the MEI interface. The driver handles authentication, versioning, and communication with the authentication firmware, which in turn coordinates with the PUnit/PCODE to apply the payload. This is a foundational component for enabling dynamic, secure, and re-entrant configuration updates on platforms like Battlemage.

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 reStructuredText 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.
