Subject: [PATCH] Display more config info at DS1302 RTC initialization

For systems which use Super capacitor or rechargable battery, trickle charge status is displayed. Good for users with ECB-RAMF for example. Trickle charge can be turned on/off with the RTC.COM utility and the status set will now be display at boot time.
