Function Selection. Strapped by VSB
Strapped to high :
DeepS5_Sel = 1:
System will enter the deep S5 state after 6 sec
delays when AC power on.
Strapped to low : (Default)
DeepS5_Sel = 0:
System will not enter the deep S5 state when AC
power on. System is in normal ACPI S5 state.
For S28/S12 Can't PWR-ON issue
