Kconfig: Drop CONFIG_CMD_DS4510

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.
