zephyr: npcx: add reset cause check
The reset cause will influence the initialization flow. We define some
of initial flow of the reset cause for the following development.
This CL include the following:
1. Add check_reset_cause() which sets the system reset flag.
2. Add chip_bbram_status_check() to clear the error status & show the
error message.
3. Add CONFIG_BOARD_RESET_AFTER_POWER_ON feature.
4. Define the initialize flow for reset cause.
BRANCH=none
BUG=b:178101173
TEST=check the following reset cause by 'sysinfo'
1. power-up
2. reset-pin reset
3. soft by 'reboot' console command
4. watchdog by 'waitms 2000'
