platform/x86/amd/pmf: Fix a potential race with policy binary sideload
The debugfs `update_policy` file is created before
amd_pmf_start_policy_engine() has completed, and thus there could be
a possible (albeit unlikely) race between sideloading a policy and the
BIOS policy getting setup.
Move the debugfs file creation after all BIOS policy is setup.
Fixes: 10817f28e533 ("platform/x86/amd/pmf: Add capability to sideload of policy binary")
