soc/mediatek/mt8192: pmic: unlock key protection before initial setting
We need to write some special values to key protection registers before applying init_setting table and lp_setting table to PMIC. Otherwise, those settings won't take effect. After applying init_setting table and lp_setting table, we lock the settings by writing zero to key protection registers.
