power: common: Print RTC when changing states.

Browse Source 
In order to help correlate EC logs with those from the kernel, it was
suggested that the EC could periodically print the RTC time.  This
commit prints out the RTC time when changing power states.

BUG=chrome-os-partner:57731
BRANCH=gru
TEST=Build and flash kevin.  Boot system up and suspend.  Verify that
RTC times are logged to the EC console.
