I noted "config SYS_EXTRA_OPTIONS string "Extra Options (DEPRECATED)" in Kconfig.
But we still have to use the CONFIG_SYS_EXTRA_OPTIONS in current configuration 
Infrastructure, unless a newer approach is available in future.

Because there are some something like 'SPL_FSL_PBL', 'NAND', 'SPIFLASH''SDCARD' which must be 
defined dynamically during build u-boot for various boot-mode in those *_defconfig files 
instead of in static include/config.h
