[meta-freescale] [meta-fsl-arm PATCH 1/3] linux-imx (3.0.35): mx6sabresd: Register SDHC3 first

[Otavio Salvador]

On sabresd boards we boot from SDHC3, so let's register it as mmc0.

Currently eMMC is mmc0 and mmc1 can be SDHC3 or SDHC2 (if present).

Registering SDHC3 is safer as we can always find the rootfs.
