mb/siemens/mc_ehl: Add external RTC RX6110SA
All the mainboards based on mc_ehl use the external RTC RX6110SA.
Enable the driver in Kconfig for all boards based on mc_ehl. In
addition, as mc_ehl1 has the RTC attached to the SMBus, add the
devicetree entry on behalf of the SMBus device 00:1f.4 for this variant.
