Using SDIO above 12 MHz causes clock glitches, which result in CRC errors (at least in embassy-stm32). In this HAL, the CRC error is not caught and write silently fails without changing any bytes on SD card.

:AFAIK, this affects all SDIOv1 peripherals including the F1 family, and possibly others.
I'm not sure about the CRC error not getting caught, but this PR at least fixes the chip errata.
