Paul Gortmaker 6200cbaf62 tty: disable unbind for old 74xx based serial/mpsc console port ... We recently got rid of some modular code in this driver and also got rid of the unused ".remove" function at the same time. Thierry noted that it was however possible to force the remove through the bind/unbind interface. Since this is a console device used on 2005 vintage 74xx based powerpc embedded targets, and is essentially always used in conjunction with SERIAL_MPSC_CONSOLE=y -- there is no sane reason anyone would ever want to unbind the builtin driver and lose the console. So we just explicitly block bind/unbind operations and prevent root from shooting themselves in the foot.
