[U-Boot] [PATCH 05/47] Kconfig: Drop CONFIG_CMD_DS4510

Mon May 15 10:57:20 UTC 2017
This option enables a command in the driver. But the functions defined by
the driver are not called anywhere else in U-Boot. So it does not seem
useful to have this driver without its commands.
Drop this option, move the header file out of the common include/
directory and make all the function static.
