[U-Boot] fsl_esdhc.c: eMMC 4.4 support?

[Andy Fleming]

Yes, that's very annoying. Of course, Freescale *does* use fsl_esdhc,
but for Power Architecture. I know that changes were submitted to
support i.MX on fsl_esdhc, too, so I don't know why they've opted to
use their own file in that tree. Hopefully they can be convinced to
add support to mainline.
