video: fix bug in cfb_console.c code
Fix bug in drawing long version/info strings: U-Boot version string like "U-Boot 2009.03-05647-g7c51e06 (Apr 23 2009 - 12:40:00) MPC83XX" is long and doesn't wrap around correctly while drawing beside the logo. Such long strings partially overwrite the logo. This patch is an attempt to fix it. Signed-off-by: Anatolij Gustschin <agust@denx.de>
