sec_touch: only update charger mode status after suspend
In normal case, touch driver will follow current power supply
notification to change corresponding charger mode. But, if this
notification is triggered after touch suspend, driver should only
update charger mode stauts to avoid any i/o transmission. And,
the latest charger mode will apply after touch driver resume.
