baseboard/kukui: correct FUSB302 VBUS turn-on delay
TCPC FUSB302 needs more time to raise VBUS to 5V. This CL
increases the delay to ensure that in SRC_DISCOVER state,
the VBUS is already raised to 5V.
BRANCH=kukui
BUG=b:152544526
TEST=Tested on kappa,
kappa source to servo-v4, and issue hard reset,
and ensure they can recover from the hard reset.
