Sometimes the debug module may not work well after resume, since it has not been correctly reset when wakeup from suspend. That cause system crash during reusme, and a 'undefined instruction' is displayed on the console. Set the GRF_FORCE_JTAG bit of RK3288_GRF_SOC_CON0 can ensure that debug modul is reset. And we can change the value of RK3288_GRF_SOC_CON0 back when system resume.
