spl_mmc: add Falcon mode support for FAT variant
If Falcon mode support is enabled (and the system isn't directed into booting u-boot), it will instead try to load kernel from CONFIG_SPL_FAT_LOAD_KERNEL_NAME file and kernel argument parameters from CONFIG_SPL_FAT_LOAD_ARGS_NAME, both from the same partition as u-boot.
