Title:
  On the StarFive VisionFive 2 the card detect GPIO is not set to input

Status in u-boot package in Ubuntu:
  Confirmed

Bug description:
  The card detect pin of the SD card slot needs to be a GPIO input. But
  command

      gpio status GPIO41

  shows that it is output.

  This leads to showing errors

      Card did not respond to voltage select! : -110

  if not SD-Card is inserted.

  Switching to input is the task of the MMC driver. Other drivers have a
  call

      gpio_request_by_name(dev, "cd-gpios", 0, &priv->cd_gpio,
  GPIOD_IS_IN);

  This is missing in drivers/mmc/snps_dw_mmc.c.
