Subject: [PATCH 4/5] thermal/drivers/mediatek/lvts: Start sensor interrupts
 disabled

Interrupts are enabled per sensor in lvts_update_irq_mask() as needed,
there's no point in enabling all of them during initialization. Change
the MONINT register initial value so all sensor interrupts start
disabled.
