baseboard/octopus: Increase delay before hibernate
Some octopus boards needs to change voltage provided form charger to
5 volts. When DUT is charged by ServoV4, voltage change request is
passed to charger connected to ServoV4. When charger changes voltage,
ServoV4 sends capabilities to DUT (see board_manage_dut_port()) and
changes state to SRC_NEGOTIATE. When DUT's EC hibernates before
negotiation is finished, ServoV4 can send hard reset. Hard reset
interrupts providing power to DUT and as a result wakes EC from
hibernation.
Above situation can be fixed by increasing delay before going to
hibernate to make sure that all PD operations have enough time to
finish.
BUG=b:161775827
BRANCH=none
TEST=Flash ToT EC on casta. Hibernate EC and check if there is no
fake wake up.
