mb/siemens/mc_ehl5: Limit eMMC speed mode to DDR50
Due to layout restrictions on mc_ehl5, the eMMC interface is limited to
operate in DDR50 mode. The alternative modes SDR104 and SDR50 are not
supported. Limit the capabilities in the eMMC controller to DDR50 mode
only so that the eMMC driver in OS will choose the right mode for
operation even if the attached eMMC card supports higher modes.
BUG=none
TEST=Boot into Linux and check dmesg output for mmc modes
