From: Dinh Nguyen <dinguyen at opensource.altera.com>

Without this patch, the booting the SOCFPGA platform would hang at the
SDMMC driver loading. There were 2 patches that caused this to happen:

- Patch 9795a846e10 "mmc: dw_mmc: remove dw_mci_of_cd_gpio/wp_gpio()" removed
  looking for "cd-gpios", since mmc_of_parse was getting called.
- Patch 3cf890fc42b "mmc: dw_mmc: Pass back errors from mmc_of_parse()" would
  hang the system at the SDMMC driver loading.

This patch will fix booting with SDMMC enabled on SOCFPGA dev kit.
