[PATCH] ColdFire serial driver fixups

A number of small ColdFire serial driver fixups:
 - use correct irq handler return type (irqreturn_t)
 - add support for mark and space parity
 - some casting to keep types clean (and remove compile warnings)
 - fix missing ";" after local tty_driver struct definition
