mb/siemens/mc_ehl2: Limit SD-Card speed modes to DDR50
Due to layout restrictions on mc_ehl2, the SD-card interface is limited
to operate in DDR50 mode. The alternative modes SDR104 and SDR50 are not
supported. Limit the capabilities in the SD card controller to DDR50
mode only so that the SD card driver in OS will choose the right mode
for operation even if the attached SD card supports higher modes.
