thermal/drivers/mediatek/lvts: Disable monitor mode during suspend
commit 65594b3745024857f812145a58db3601d733676c upstream.
When configured in filtered mode, the LVTS thermal controller will
monitor the temperature from the sensors and trigger an interrupt once a
thermal threshold is crossed.
Currently this is true even during suspend and resume. The problem with
that is that when enabling the internal clock of the LVTS controller in
lvts_ctrl_set_enable() during resume, the temperature reading can glitch
and appear much higher than the real one, resulting in a spurious
interrupt getting generated.
Disable the temperature monitoring and give some time for the signals to
stabilize during suspend in order to prevent such spurious interrupts.
