touchscreen: Add device_touchscreen_set_off_bind_with_display()

Supports touchscreen off operation policy as setter.
Combines touchscreen off operation with display off operation.
If sets touchscreen off mode value as true,
When the display state goes to off, touchscreen will be disabled(off state).
That means touchscreen always follows display off operation.
If touchscreen off mode value is set as false,
Then touchscreen will ignore display off state independently.
