Xiang Xiao 404de093a1 fs: Flush the file system cache in BOARDIOC_POWEROFF too
and remove the check of SYS_DOWN since it defines to SYS_RESTART in reboot_notifer.h:
  #define SYS_DOWN        0x0001     /* Notify of system down */
  #define SYS_RESTART     SYS_DOWN
  #define SYS_HALT        0x0002     /* Notify of system halt */
  #define SYS_POWER_OFF   0x0003     /* Notify of system power off */
