[v2,1/2] platform/x86/amd/pmf: Propagate PMF-TA return codes

Commit Message

In the amd_pmf_invoke_cmd_init() function within the PMF driver ensure
that the actual result from the PMF-TA is returned rather than a generic
EIO. This change allows for proper handling of errors originating from the
PMF-TA.
