mb/siemens/mc_ehl2: Change to new RTC RV3028-C7
Since the latest redesign a new RTC was introduced on mc_ehl2. Instead
of the old RX6110SA the new Micro Crystal RTC RV3028 is used now. Since
the address of this new RTC conflicts with an EEPROM on I2C bus 2, the
new RTC was moved to I2C bus 1.
As the mainboard is not finished yet, there are no incompatibility
issues with this change. Every new mainboard will have the new RTC and
the older mainboards are not delivered yet.
