    The SD-Card bus generates EMI problems for higher Bus frequencies. Thsus
    limit the SD-Card bus to 50MHz.
    
    From our expectations this should mean, that DDR50 is available.
    See also https://en.wikipedia.org/w/index.php?title=SD_card&oldid=1112713978#Power_consumption
    
    In the drivers/mmc/host/sdhci-esdhc-imx.c driver, however, the DDR50 is
    only advertised when the pinctrl state_100mhz is available.
