ENGR00315894-12 i.mx6:sabreauto/sabresd: Change the MMC settings

1. Change CONFIG_MMCROOT to mmcblk0p2.
   Kernel always sets the first availiable MMC/SD device to mmcblk0
2. Make the MMC ENV DEV/PART independent of ENV_IS_IN_MMC
3. Add the CONFIG_SYS_MMC_ENV_PART to 0 (user area) for u-boot env saving.

   CONFIG_SYS_MMC_ENV_PART: was used to tell the u-boot which
   emmc (boot)partition to be used for the env_mmc.Usually, the
   emmc card will have 2 boot partitions, boot1 and boot2.

       0: means user area
       1: means boot partition 1
       2: means boot partition 2

   If user want to use the boot partition to store the u-boot env, please
   change the CONFIG_SYS_MMC_ENV_PART to which boot partition you want.

4. Add the CONFIG_SYS_MMC_IMG_LOAD_PART for the partition number where the kernel
   and DTB will load from. At default, it is the first partition in VFAT format.
