lib: Add real-time-clock functions
Add functions to convert between seconds and a struct rtc_time. Also
add a function that can display the time on the console.
BUG=chrome-os-partner:52220
BRANCH=none
TEST=(partial) with future commits and after setting RTC on the EC:
boot on gru into linux shell, check firmware log:
localhost ~ # grep Date: /sys/firmware/log
Date: 2016-06-20 (Monday) Time: 18:01:44
Then reboot ~10 seconds and check again:
localhost ~ # grep Date: /sys/firmware/log
Date: 2016-06-20 (Monday) Time: 18:01:54
