`cb_mutex` was introduced in commit9e0894d070("platform/x86/amd/pmf: Enable Custom BIOS Inputs for PMF-TA") to prevent conccurrent access for BIOS inputs. It however isn't initialized and so on use it may lead to a NULL pointer dereference. Add code to initialize on probe and clean up on destroy.

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.
