This series contains the change for selection of bus speed mode.
Previous implementation is complicated and some sequence is duplicated.
And specially, HS400 mode eMMC5.0 is introduced this time.
This patch-set has been tested in Exynos SoC.
Note:
As RS9113 wireless driver has been introduced newly in Linux-3.15-rc1,
we meet some dependency with this patch-set
which has been in the works all the while.
Thus, related modification is applied through " mmc: drop the speed
mode of card's state"
