[U-Boot] [PATCH 5/6] i.mx: fsl_esdhc: add the i.mx6q support

[Jason Liu]

The mmc host controller on the i.mx6q is called usdhc which
is redesigned based on the freescale esdhc controller.

The usdhc controller is almost compatible with esdhc except
it adds one misc control register from user using experience.
