This CONFIG_SYS_ODROID_USB options is more like and compile time flag
defined in odroid.h and not on any other boards, so this flags add
guard to the code.

At the end of  u-boot compilation it would prompt that new config
option is added
please add this to some Kconfig so that it could be selected via make menuconfig

See the link below, why I chose this options.
