Subject: [PATCH] drivers/power/pm_initialize.c:  Fix pm_domain_s.stime unint
 caused time error.  Bug deatil:

  1. open CONFIG_DEBUG_FEATURES CONFIG_SYSTEM_TIME64 CONFIG_CLOCK_MONOTONIC
     ==> INITIAL_SYSTEM_TIMER_TICKS very big data, not zero
  2. close CONFIG_SCHED_TICKLESS
     ==> use g_system_timer as system clock
  3. pm_domain_s.stime init to zero
  4. clock_systimer() - pm_domain_s.stime get big data, error
