vt82c686: Convert debug printf to trace points
Drop DPRINTF and use trace functions instead. Two debug messages about unimplemented registers could be converted to qemu_log_mask() but in reality all registers are currently unimplemented (we just store and return values of writable regs but do nothing with them). As we already trace register access there's no need for additional debug messages so these are just removed and a comment is added as a reminder.
