drivers/console: Use cursor save/restore escape sequences Instead of keeping track how many characters we need to move back to get to the original position, take advantage of the save/restore escape sequences. This allows us to drop the extra 'i' variable from both insert_char() as well as del_char(). Change-Id: I69a2b5ea12ec2a7a2e4d519b55e4c737b5d5d25a Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
