mmc: Consolidate emmc tuning blocks
The same tuning block exists in the dw_mmc h.c and sdhci-msm.c files. Move these into mmc.c so that they can be shared across drivers. Reported-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
