system: Remember if reset was due to AP watchdog triggering
On MT8183, when EC detects a watchdog reset, EC needs to reboot
itself in preparation for the next boot. This means that AP loses
the reset cause (as AP system reset is toggled), and, therefore,
we need to save the reset reason in the EC.
BRANCH=none
BUG=b:109900671
TEST=apshutdown, powerb, see that reset reason is: reset-pin
TEST=Use test-wd from bug. Reset reason: reset-pin ap-watchdog
