[PATCH v2 12/31] tty: tty_driver: move TTY macros to the top

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

So that they can be referenced in structs once converted to enums (in
the next patches).

+/**
+ * DOC: TTY Driver Flags
+ *
+ * TTY_DRIVER_RESET_TERMIOS
+ *	Requests the tty layer to reset the termios setting when the last
+ *	process has closed the device. Used for PTYs, in particular.
+ *
+ * TTY_DRIVER_REAL_RAW
+ *	Indicates that the driver will guarantee not to set any special
+ *	character handling flags if this is set for the tty:
+ *
+ *	``(IGNBRK || (!BRKINT && !PARMRK)) && (IGNPAR || !INPCK)``
+ *
+ *	That is, if there is no reason for the driver to
+ *	send notifications of parity and break characters up to the line
+ *	driver, it won't do so.  This allows the line driver to optimize for
+ *	this case if this flag is set.  (Note that there is also a promise, if
+ *	the above case is true, not to signal overruns, either.)
+ *
+ * TTY_DRIVER_DYNAMIC_DEV
+ *	The individual tty devices need to be registered with a call to
+ *	tty_register_device() when the device is found in the system and
+ *	unregistered with a call to tty_unregister_device() so the devices will
+ *	be show up properly in sysfs.  If not set, all &tty_driver.num entries
+ *	will be created by the tty core in sysfs when tty_register_driver() is
+ *	called.  This is to be used by drivers that have tty devices that can
+ *	appear and disappear while the main tty driver is registered with the
+ *	tty core.
+ *
+ * TTY_DRIVER_DEVPTS_MEM
+ *	Don't use the standard arrays (&tty_driver.ttys and
+ *	&tty_driver.termios), instead use dynamic memory keyed through the
+ *	devpts filesystem. This is only applicable to the PTY driver.
+ *
+ * TTY_DRIVER_HARDWARE_BREAK
+ *	Hardware handles break signals. Pass the requested timeout to the
+ *	&tty_operations.break_ctl instead of using a simple on/off interface.
+ *
+ * TTY_DRIVER_DYNAMIC_ALLOC
+ *	Do not allocate structures which are needed per line for this driver
+ *	(&tty_driver.ports) as it would waste memory. The driver will take
+ *	care. This is only applicable to the PTY driver.
+ *
+ * TTY_DRIVER_UNNUMBERED_NODE
+ *	Do not create numbered ``/dev`` nodes. For example, create
+ *	``/dev/ttyprintk`` and not ``/dev/ttyprintk0``. Applicable only when a
+ *	driver for a single tty device is being allocated.
