a20s: Fix watchdog issue

Browse Source 
This commit fixes the Watchdog Timer Software problem by disabling it.

When the Watchdog Timer expires or crashes causes the device (in this case: Samsung Galaxy A20s) to reboot, and is fixed by just disabling it.

An example of kernel panic log:
[  115.680218] I[5:IntentService[D: 5621] Kernel panic - not syncing: Software Watchdog Timer expired
[  117.139710] I[5:IntentService[D: 5621] sec_debug_panic_handler :Software Watchdog Timer expired
[  117.141840] Causing a watchdog bite!

GSI used to test whether the problem has been fixed: https://sourceforge.net/projects/gsi-projects/files/v413/ArrowOS-12.1/ArrowOS-12.1-arm64_bgN-vndklite-Unofficial.img.xz/download
