Support IPMI Sync RTC time to BMC command

Implement the IPMI command to sync RTC time to BMC as follow:
- In the NTP mode, does not set the system time
- In the NTP mode is disabled, set the system time using hwclock

Tested:
1. Check the NTP mode is active
   # timedatectl | grep "NTP service"
     NTP service: active
2. Change time on Host
   # date --set="20190601 17:30"
3. Sync the system time to RTC on Host
   # hwclock --systohc
4. Run ipmi command to sync RTC to BMC
   # ipmitool raw 0x3c 0xf9
   Unable to send RAW command (channel=0x0 netfn=0x3c lun=0x0 cmd =
   0xf9 rsp=0x1): Unknown (0x01)
5. Check the system time via IPMI/Webui or #date command in bmc console.
   # date
   # ipmitool sel time get
   The system time does not change.
6. Disable NTP service and repeat test cases #4, #5
   # systemctl stop systemd-timesyncd.service
   # ipmitool raw 0x3c 0xf9
   Make sure the system time can be change.
