mb/siemens/mc_ehl2: Move RTC RX6110SA from SMBus to I2C2
This board has the RTC RX6110SA connected to the I2C2 instead of SMBus
as in mc_ehl1. Set the bus speed for I2C2 to 100 kHz, since this RTC
only supports the standard speed.
TEST:
- Console Log shows no errors for RX6110SA during I2C2 init
- Finalize device for I2C 00:32 shows correct date and time
