On the MK808 only a microSD slot is connected with the SDMMC Host

so remove the cap-mmc-highspeed property from the &mmc0 node.
Why, does it do any harm?
Harm not. Example rk3066 u-boot:
sd card: widths [4, 1, ] modes [MMC legacy, SD High Speed (50MHz), UHSsd_select_mode_and_width
SDR12 (25MHz), UHS SDR25 (50MHz), ]
host: widths [4, 1, ] modes [MMC legacy, MMC High Speed (26MHz), SD
High Speed (50MHz), MMC High Speed (52MHz), ]
trying mode SD High Speed (50MHz) width 4 (at 50 MHz)
I would say only advertise host capabilities that are under normal
circumstances occur. How realistic is it to use a TF/Micro SD TO SD Card
Extension Cable Adapter (giggle) for a deprecated mmc card?
