[U-Boot] [RFC 4/6] configs: exynos: Add new CONFIG_SYS_ODROID_USB config option

[Anand Moon]

Add new CONFIG_SYS_ODROID_USB flag to avoid compliation
error on other development boards.

Fix below compilation error:
Error: You must add new CONFIG options using Kconfig
The following new ad-hoc CONFIG options were detected:
CONFIG_SYS_ODROID_USB
