commit376a8c2a14("platform/x86/amd/pmf: Update PMF Driver for Compatibility with new PMF-TA") added support for platforms that support an updated TA, however it also exposed a number of platforms that although they have support for the updated TA don't actually populate a policy binary. Add an explicit check that the policy binary isn't empty before initializing the TA.

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.
