fix terminal output formatting
=== Q: How to enter RTC mode? ===
By default, iMX6 RTC driver is built into the Linux kernel. Upon power-up, it prints informational messages that look like this.
 <preclass="board-terminal">
[ 2.017007] snvs_rtc 20cc034.snvs-rtc-lp: rtc core: registered 20cc034.snvs-rtc-lp as rtc0
[ 2.025312] snvs_rtc 20cc034.snvs-rtc-lp: configured with power off disabled
To initialize it, please use these commands:
 <preclass="board-terminal">
root@axel-lite:~# date 053014172016
Mon May 30 14:17:00 UTC 2016
To enter RTC mode, use the <code>shutdown</code> command as shown in the following example:
 <preclass="board-terminal">
root@axel-lite:~# shutdown -h now
[ 234.876402] System halted.
</pre>
 
If a coin call battery is connected to PMIC_LICELL, RTC will be kept alive even if 3V3VIN voltage is removed. Please refer to [[Integration_guide_(Axel)#Real-time_clock_.28RTC.29|these important issues]] related to RTC power handling.
