Due to MHI bugs, at the moment we are not able to shutdown and fully power off the device. As a workaround we put firmware to WoW state to make sure no unexpected activities while host is in suspend. With all suspend/resume functionality implemented, we change supports_suspend to true for WCN7850 to make it work.
