common/lcd: Add command for writing to lcd-display

Browse Source 
Sometimes we do not want redirect u-boot's console to screen but anyway we want
write out some status information out of a u-boot script to the display.

So we cannot use the normal "echo ....", instead we write explicitly using
"lcdputs ..." for writing to the actual cursor position on LCD.
