power/mt8183: Pulse PMIC_FORCE_RESET_ODL for 10s to force reset
power/mt8183: Pulse PMIC_FORCE_RESET_ODL for 10s to force reset

On forced shutdown, assert PMIC_FORCE_RESET_ODL for 10 seconds.
Sometimes, just a short 5ms pulse is enough to shut down the PMIC,
but we have seen boards where it is required to assert force
reset for a longer time, else the PMIC would immediately power
back up.

BRANCH=none
BUG=b:117747023
TEST=Boot kukui (current AP FW that has no PMIC code yet), type
     apshutdown in EC console, see that the PMIC is shut down.
