soc/mediatek/mt8189: Enable MEDIATEK_WDT_RESET_BY_SW

Browse source 
For MT8189, watchdog external reset is enabled by kernel configuration,
and EC ignores the reset signal AP_PMIC_WDTRST_L. Therefore, enable
MEDIATEK_WDT_RESET_BY_SW to allow triggering the secondary watchdog
reset via software instead of watchdog hardware.

TEST=emerge-skywalker coreboot
TEST=watchdog event added to eventlog on WDT timeout
TEST=cbmem logs preserved on WDT timeout
