Mengqi Zhang 493a8172e5 mmc: core: Add HS400 tuning in HS400es initialization
commit 77e01b49e35f24ebd1659096d5fc5c3b75975545 upstream.

During the initialization to HS400es stage, add a HS400 tuning flow as an
optional process. For Mediatek IP, the HS400es mode requires a specific
tuning to ensure the correct HS400 timing setting.
