This adds HS400 mode support for exynos dw_mmc host controller.

Currently tested on Exynos5800-peach-pi platform for HS400 mode.
Tested HS200 mode with this series applied, HS200 still works.

Appreciate testing on other exynos5/7 platform which supports emmc5.0

I will test this patch on exynos5/7 board.
