mb/siemens/mc_apl2: Limit SD-Card speed to DDR50
Due to PCB limitations the SD-Card interface is not able to operate with the highest frequency reliably. The OS driver will switch to the highest mode if a SD-Card is attached which supports this high frequency mode. In order to work around this PCB limitation disable the high frequency modes in the controller capabilities (SDR104 and HS400 mode) and leave SDR50 and DDR50 enabled.
