AMD Family 15tn: Set the default return value as AGESA_SUCCESS instead of TRUE

The default return value should be AGESA_SUCCESS, which is zero. If it was set as TRUE,
    the AGESA wrapper would think it was AGESA_UNSUPPORTED. That would make no sense. And it
    would produce ASSERT warning in AGESA wrapper.

On my parmer board, with Engine sample processor, it can not create the correct DMI table.
    Routine initlate will return AGESS_ERROR.
    ------Serial message---------
    ASSERTION FAILED: file 'src/mainboard/amd/parmer/agesawrapper.c',  line 427
    DmiTable:100123c3, AcpiPstatein: 10010126, AcpiSrat:0,AcpiSlit:0, Mce:100111ba, Cmc:1001127c,Alib:1001ccd4, AcpiIvrs:0 in agesawrapper_amdinitlate
    agesawrapper_amdinitlate failed: 5
    -----------------------------
    I believe the processor with acceptable name string will create the right DMI.
