mb/siemens/mc_ehl: Make DRAM population configurable
There can be mainboard variants, which are only equipped with
half-populated DRAM. For this reason, the meminit parameter for
populatation should be adjustable. The default setting remains at
full-populated DRAM. At mainboard variant level a different selection
via individual input paths can be made.
