Problem:
When debugging, there will be a lot of printing to be
output after the panic, so it is very time-consuming.
In order to prevent the watchdog from causing a reset,
we stop it after panic.
Solution:
Add functions and provide two ways to enable:
1. Add wdt_stop_after_panic=1 to bootargs.
2. echo 1 > /sys/module/amlogic_watchdog/parameters/stop_after_panic
