mc_tcu3: Do not abort initialization of PTN3460 when HW-ID is missing

Do not abort the initialization of PTN3460 if HW-ID could not be
    retrieved and just assume that the HW-ID does not match 7.9.2.0.
    In this case PTN3460 will be setup to a working condition even
    if this field is missing.
    This makes this driver more robust with faulty blocks.
