stable inclusion from linux-4.19.207 commit ae2f93104e8cd0fac969d471f3396c073956d5af
--------------------------------
[ Upstream commit 245ca2cc212bb2a078332ec99afbfbb202f44c2d ]
Use 50ms as default timeout value and the time clock is 32768HZ. The original value of WDG_LOAD_VAL is not correct, so this patch fixes it.
