vilboz: Enable LTE GPIO control
Power-on and Resume form S3:
Delay 10ms to pull high LTE_FCPO after LTE_EN is high.
Suspend and Power-off:
Delay 20ms to pull down LTE_FCPO after SLP_S3_L is low.
Delay 100ms to pull down LTE_EN after LTE_FCPO is low.
BUG=b:173490220
BRANCH=Zork
TEST=Measure waveform for LTE_FCPO GPIO control
