[U-Boot] [PATCH] Allow the "reset" command to be omitted with CONFIG_CMD_RESET

[Kyle Moffett]

This new #define is set in config_cmd_defaults.h (which is automatically
included on every board by "mkconfig"), but this allows boards to elect
to omit the "reset" command if necessary with "#undef CONFIG_CMD_RESET".
