soc/mediatek/mt8186: Fix issue of clearing watchdog status
The implementation of clearing watchdog status is wrong in CB:58835.
The value written to the 'wdt_mode' register should be
'wdt_mode | 0x22000000' instead of 'wdt_status | 0x22000000'.
BUG=b:204229208
TEST=check watchdog status is cleared.
