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.
