tty: move Kconfig entries into drivers/tty from drivers/char

The Kconfig options for the drivers/tty/ files still were hanging around
in the "big" drivers/char/Kconfig file, so move them to the proper
location under drivers/tty and drivers/tty/hvc/

-        ---help---
-          If you say Y here, you will get support for terminal devices with
-          display and keyboard devices. These are called "virtual" because you
-          can run several virtual terminals (also called virtual consoles) on
-          one physical terminal. This is rather useful, for example one
-          virtual terminal can collect system messages and warnings, another
-          one can be used for a text-mode user session, and a third could run
-          an X session, all in parallel. Switching between virtual terminals
-          is done with certain key combinations, usually Alt-<function key>.
-
-          The setterm command ("man setterm") can be used to change the
-          properties (such as colors or beeping) of a virtual terminal. The
-          man page console_codes(4) ("man console_codes") contains the special
-          character sequences that can be used to change those properties
-          directly. The fonts used on virtual terminals can be changed with
-          the setfont ("man setfont") command and the key bindings are defined
-          with the loadkeys ("man loadkeys") command.
-
-          You need at least one virtual terminal device in order to make use
-          of your keyboard and monitor. Therefore, only people configuring an
-          embedded system would want to say N here in order to save some
-          memory; the only way to log into such a system is then via a serial
-          or network connection.
-
-          If unsure, say Y, or else you won't be able to do much with your new
-          shiny Linux system :-)

-        ---help---
-          The system console is the device which receives all kernel messages
-          and warnings and which allows logins in single user mode. If you
-          answer Y here, a virtual terminal (the device used to interact with
-          a physical terminal) can be used as system console. This is the most
-          common mode of operations, so you should say Y here unless you want
-          the kernel messages be output only to a serial port (in which case
-          you should say Y to "Console on serial port", below).
-
-          If you do say Y here, by default the currently visible virtual
-          terminal (/dev/tty0) will be used as system console. You can change
-          that with a kernel command line option such as "console=tty3" which
-          would use the third virtual terminal as system console. (Try "man
-          bootparam" or see the documentation of your boot loader (lilo or

-         The virtual terminal is the device that interacts with the physical

+          module.
