asus-wmi: use ASUS_WMI_METHODID_DSTS2 as default DSTS ID.
commit 63a78bb1051b240417daad3a3fa9c1bb10646dca upstream. According to responses from the BIOS team, ASUS_WMI_METHODID_DSTS2 (0x53545344) will be used as future DSTS ID. In addition, calling asus_wmi_evaluate_method(ASUS_WMI_METHODID_DSTS2, 0, 0, NULL) returns ASUS_WMI_UNSUPPORTED_METHOD in new ASUS laptop PCs. This patch fixes no DSTS ID will be assigned in this case.
