um: clean Kconfig up a bit

* kill duplicates with drivers/char/Kconfig
* take watchdog one into drivers/watchdog/Kconfig
* take mmapper to arch/um/Kconfig.um
* rename Kconfig.char menu to "UML Character Devices"

-         A pseudo terminal (PTY) is a software device consisting of two

-         a physical terminal; the master device is used by a process to
-         read data from and write data to the slave, thereby emulating a
-         terminal. Typical programs for the master side are telnet servers
-         and xterms.

-         Linux has traditionally used the BSD-like names /dev/ptyxx for
-         masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
-         has a number of problems. The GNU C library glibc 2.1 and later,
-         however, supports the Unix98 naming standard: in order to acquire a
-         pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
-         terminal is then made available to the process and the pseudo
-         terminal slave can be accessed as /dev/pts/<number>. What was
-         traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
