Just like the Quartz64 Model B the previously stated speed of sdr-104
in soquartz is too high for the hardware to reliably communicate with
some fast SD cards.
Especially on some carrierboards.
Lower this to sd-uhs-sdr50 to fix this.

Makes sense, considering the problems we're having with other boards.
We should probably stop using sdr104 altogether on Rockchip, at least
until they release a chip that improves on the limitations of pinctrl
speed. Considering the frequency cap it isn't that much of a hit.
I agree, better have a safe default.

Thank you for the Ack.
