baseboard/octopus: Enable CONFIG_BOARD_HAS_RTC_RESET
Add a helper function to reset the RTC using EC_PCH_RTCRST GPIO.
Enable the config to use the hardware support to reset the RTC.
BUG=b:119678692
BRANCH=octopus
TEST=make -j buildall && Boot to ChromeOS. Create a forced scenario to
trigger an RTC reset and ensure that EC does not get reset while the SoC
boots to ChromeOS. Execute warm reboot from AP, cold reboot from EC and
wake from ec hibernate (10 iterations each) and suspend_stress_test for
50 iterations successfully.
