Falcon mode is very useful in improving boot speed. A question that Falcon mode asks is "Where do I look for the kernel". With MMC boot media, the correct answer is CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR. The scope of this patch is to move this to Kconfig. It is possible for a system to support Falcon mode from NOR but not MMC. In that case, mmc_load_image_raw_os() would not be used. To address this, conditionally compile mmc_load_image_raw_os() when SPL_FALCON_BOOT_MMCSD, instead of SPL_OS_BOOT.
