mb/siemens/mc_bdx1: Set up RTC backup mode to primary cell
The used RTC6110SA has issues to enter backup mode when the power supply
decreases too slow when the mainboard is turned off. Switch to backup
mode "primary cell" to make sure backup mode will be entered correctly
on power-off. In addition set IOCUTEN to minimize the backup current
consumption of the RTC.
