[PATCH RESEND 5/5] mmc: add support for HS400 mode of eMMC5.0

This patch adds HS400 mode support for eMMC5.0 device. HS400 mode is high speed DDR interface timing from HS200. Clock frequency is up to 200MHz and only 8-bit bus width is supported. In addition, tuning process of HS200 is required to synchronize the command response on the CMD line because CMD in
