b49a0ff732 tty: tty_buffer: use __tty_insert_flip_string_flags() in tty_insert_flip_char() 
Use __tty_insert_flip_string_flags() for the slow path of
tty_insert_flip_char(). The former is generic enough, so there is no
reason to reimplement the injection once again.

So now we have a single function stuffing into tty buffers.

c26405fd28 tty: tty_buffer: unify tty_insert_flip_string_{fixed_flag,flags}() 
They both do the same except for flags. One mem-copies the flags from
the caller, the other mem-sets to one flag given by the caller. This can
be unified with a simple if in the unified function.

b96cd8b05e Documentation: move tty to driver-api 
Based on discussion starting as 87mthw2o93.fsf@meer.lwn.net, let's move
the tty documentation to driver-api. It's more appropriate there.
