hvc_console: Add tty driver flag TTY_DRIVER_RESET_TERMIOS
After a tty hangup() or close() operation, processes might not reset the
termio settings to a sane state. In order to reset the termios to its
default settings the tty driver flag TTY_DRIVER_RESET_TERMIOS has been added.
TTY driver flag description from include/linux/tty_driver.h:
TTY_DRIVER_RESET_TERMIOS --- requests the tty layer to reset the
termios setting when the last process has closed the device.
Used for PTY's, in particular.
