mb/siemens/mc_ehl: Add FIVR config to devicetree for all variants
Add a config for FIVR in devicetree for both, mc_ehl1 and mc_ehl2
variants in order to provide the real delay value for the VCC supply
rail. This delay is needed to enable proper switching between different
VCC levels based on current system state.
