platform/x86/amd/pmf: Fix return value of amd_pmf_start_policy_engine()
amd_pmf_start_policy_engine() returns an negative error code upon
failure, so the TA_PMF_* error codes cannot be used here.
Return -EIO instead. Also stop shadowing the return code in
amd_pmf_get_pb_data().
Compile-tested only.
