configs: sama5d27_som1_ek: Add defconfig for ENV/boot from uSD
This adds a defconfig for sama5d27_som1_ek board to get environment from
uSD. The defconfig is made from sama5d27_som1_ek_mmc_defconfig, with
'bootcmd' and 'bootargs' changed to kernel, device-tree and rootfs from
uSD. The environment is expected to be found in uSD's FAT partition.
