Zexin Wang 2bec5a9d9a soc/mediatek/mt8189: Check eFuse ECC in WDT init 
When the number of eFuse reads exceeds a certain limit (with a maximum
of 20 million), a bit flip from 1 to 0 may happen. When that happens,
the bit flip will be automatically corrected by the eFuse hardware via
ECC (Error Correction Code), and the EFUSE_ECC_ERR register bit will be
set for the software to decide how to handle that.

Therefore, this patch adds a check for the EFUSE_ECC_ERR register bit.
If it's set due to a bit flip instead of a real error, we simply clear
it to avoid triggering a WDT reset.

BUG=b:379008996
BRANCH=none
TEST=build passed and check the WDT status debug log. This log is added
in local for test only.
