rockchip: disable UHS speed for ROC-RK3328-CC
The previously stated speed of sdr-104 in is too high for the hardware
to reliably communicate with some fast SD cards.
Rockchip boards have a common bug when operating uhs speed, which will
hang the system during a soft reboot.
To be on the safe side, lower the speed to workaround.
