[U-Boot] [PATCH v1 03/11] Revert "mmc: Add a new callback function to perform the 74 clocks cycle sequence"

[Jean-Jacques Hiblot]

This reverts commit 318a7a576bc49aa8b4207e694d3fbd48c663d6ac.

The last and only user of this callback had been the omap_hsmmc driver.
It is not used anymore. Removing the callback.
