Add support to boot Linux directly from U-Boot SPL via eMMC (or RAW SD Cards) and FAT SD Cards. Jump into full U-Boot if a corresponding button is pressed.
Also define new CONFIG_BOOTCOMMAND to add ability for full U-Boot to boot Linux via eMMC (or RAW SD cards) and FAT SD Cards in case of using CONFIG_SPL_OS_BOOT feature. Set MMCDEV_DEFAULT to 1 in CONFIG_EXTRA_ENV_SETTINGS, since the target device is mmc1 (eMMC).
Also enable the spl command in the full U-Boot so the kernel parameter area snapshot can be created.

Why are we taking env in eMMC support away by default? Is this related to using the boot partitions? If so, shouldn't we re-work this to fit that use as well (maybe use the 2nd boot partition for env?). Thanks.
