volteer: increase TCPC low power mode exit delay
Increase the low power mode exit delay on Volteer to 50ms. The ps8815
TCPC in particular needs this extra time to work consistently with
non-PD chargers.
This change also ensures the low power mode exit timer is reset anytime
the TC enters the TC_LOW_POWER_MODE state.
BUG=b:160182500
BRANCH=none
TEST=make buildall
TEST=Insert 15W non-PD charger on Volteer: repeat 10 times
TEST=Insert USB type-A (7.5W advertised) on Volteer: repeat 10 times
