mb/prodrive/atlas: Enable GPP_B14 buzzer support
Per Intel doc 621483, 26.1.1 - NMI_STS_CNT, 8254 timer is required for Speaker Data output (buzzer) at GPP_B14 NF1, as it is using 8254 timer counter 2 output. However when 8254 timer is used, S0ix will not work as 8254 has to be gated instead. For further info on s0ix requirements, refer to Intel doc 610002 (Modern Standby Unified Checklist). This CL also disables s0ix because it is not required by the platform.
