Split the display command into generic interface and hardware-specific realization for PDSP188x LED display found on hmi1001 and manroland boards. Simple interface for LED displays is defined in include/led-display.h and described in doc/README.LED_display. Driver-specific implementation was moved into drivers/misc/pdsp188x.c file (enabled with CONFIG_PDSP188x set). Signed-off-by: Ilya Yanok <yanok@emcraft.com>
