[U-Boot] [PATCH 0/4] mmc: Fix recognition and selection of Dual Data Rate mode

This set of commits fixes some problems and drawbacks in current implementation of MMC Dual Data Rate mode support.

These changes were tested not with dw_mmc driver, but with DDR mode support implementation for fsl_esdhc driver, ported from Freescale's 2009.08 based version and not yet submitted to the community.
