ENGR00299848 ARM:imx6 Change static environment SD/MMC storage to dynamic
imx6 boards (sabresd, sabreauto, arm2 and slevk) have multiple SD/MMC ports to boot.
But current uboot hard code the SD/MMC port for environment variables storage. So
if customer changes a port without modifying the configuration "CONFIG_SYS_MMC_ENV_DEV",
error will issue at saving and loading environment.
Implement a mechanism to detect SD/MMC port from SRC SMBR register, and override the
default "mmc_get_env_devno". The "board_late_mmc_env_init" is used to set "mmcdev"
when booting from SD/MMC port. Finally after booting from SD/MMC, the environment storage
device and "mmcdev" are both set to current SD/MMC port. Customers don't need to re-build
the image if booting from different SD/MMC port.
This patch also adds SD1 and SD3 support to imx6slevk BSP, and adds support for sabreauto
SD1 slot on base board.
