Samsung enables FOD in TS driver (fod_enable) at all times except
a small number of optical FOD sensor that doesn't have BiometricFeature
.FEATURE_SUPPORT_AOD. As optical type sensor support is not implemented
currently, this HAL is only used on device that has FOD always-on.
This change follows behavior of stock firmware and without toggling of
FOD enable state FOD should be more stable.
Plus it allows setInteractive and config_powerDecoupleInteractiveModeFromDisplay
to function properly with FOD. Currently setInteractive(0) happens before
a onShowFODView (which is the current point to call fod_enable) can be
triggered by the Doze, as TS driver only handles command when it is enabled,
FOD doesn't work when there is a setInteractive(0) that disables TS.
