MLK-16496-2 mmc: fsl_esdhc: add hs400 es mode support

Add HS400 ES mode support.

The flow is same as mmc_select_hs400es in kernel drivers/mmc/core/mmc.c.
With HS400 ES, there is no tuning needed.

With Toshiba 32GB Automotive eMMC5.1 on 8QXP ARM2 board, speed test:
'time mmc read 0x90000000 0 0x200000' shows that speed is 282MB/s.
