common/lcd: Add command for setting cursor within lcd-console
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. To define the specific position of the string to be written, we have to set the cursor with "setcurs" before writing. Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at>
