Compiling the display command leads to an error
undefined reference to `display_set'
No implementation of display_set() exists in U-Boot.
Eliminate the `display` command as well as the accompanying files.

-LED display internal API
-=======================================
-
-This README describes the LED display API.
-
-The API is defined by the include file include/led-display.h
-
-The first step in to define CONFIG_CMD_DISPLAY in the board config file.
-Then you need to provide the following functions to access LED display:
-
-void display_set(int cmd);
-
-This function should control the state of the LED display. Argument is
-an ORed combination of the following values:
- DISPLAY_CLEAR -- clear the display
- DISPLAY_HOME -- set the position to the beginning of display
-
-int display_putc(char c);
-
-This function should display it's parameter on the LED display in the
-current position. Returns the displayed character on success or -1 in
-case of failure.
-
-With this functions defined 'display' command will display it's
-arguments on the LED display (or clear the display if called without
-arguments).
