Sebastian Huber 7fd5e89c96 termios: Partially hide rtems_termios_tty 
Move interrupt lock to device context and expose only this structure to
the read, write and set attributes device handler.  This makes these
device handler independent of the general Termios infrastructure
suitable for direct use in printk() support.
