[PATCH v5 0/2] mmc: dw_mmc: exynos: Add HS400 support

[Alim Akhtar]

This adds HS400 mode support for exynos dw_mmc host controller.

Currently tested on Exynos5800-peach-pi and Exyons7 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

Changes in V5:
	* Enable HS400 on Exynos5800-peach-pi boards
	* Addressed other review comments from Jaehoon Chung

Changes in V4:
	* drop the idea of changing existing binding for ciu_div as per [1]
        * addressed comments from Jaehoon Chung [2]
