[PATCH 5/6] mmc: sdhci-esdhc-imx: add imx6sx support

[Dong Aisheng]

From: Dong Aisheng <b29396 at freescale.com>

The imx6sx usdhc is derived from imx6sl, the difference is minor.
imx6sx have the errata ESDHC_FLAG_ERR004536 fixed.
So introduce a new compatible string for imx6sx to distinguish them.
