drivers/platform/x86/amd: pmf: Check for invalid Smart PC Policies
[ Upstream commit 8e81b9cd6e95188d12c9cc25d40b61dd5ea05ace ]
commit 376a8c2a14439 ("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.
