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.
