Huang, Sean Z 0436ac1b00 drm/i915/pxp: Implement funcs to create the TEE channel
Implement the funcs to create the TEE channel, so kernel can
send the TEE commands directly to TEE for creating the arbitrary
(default) session.

v2: fix locking, don't pollute dev_priv (Chris)

v3: wait for mei PXP component to be bound.

v4: drop the wait, as the component might be bound after i915 load
completes. We'll instead check when sending a tee message.

v5: fix an issue with mei_pxp module removal

v6: don't use fetch_and_zero in fini (Rodrigo)

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.
