[PATCH] devfs: remove devfs from Kconfig preventing it from being built

Here's a much smaller patch to simply disable devfs from the build.  If
this goes well, and there are no complaints for a few weeks, I'll resend
my big "devfs-die-die-die" series of patches that rip the whole thing
out of the kernel tree.

-	  This is support for devfs, a virtual file system (like /proc) which
-	  provides the file system interface to device drivers, normally found
-	  in /dev. Devfs does not depend on major and minor number
-	  allocations. Device drivers register entries in /dev which then
-	  appear automatically, which means that the system administrator does
-	  not have to create character and block special device files in the
-	  /dev directory using the mknod command (or MAKEDEV script) anymore.

-	  This is work in progress. If you want to use this, you *must* read
-	  the material in <file:Documentation/filesystems/devfs/>, especially
-	  the file README there.
-
-	  Note that devfs no longer manages /dev/pts!  If you are using UNIX98
-	  ptys, you will also need to mount the /dev/pts filesystem (devpts).

-	  Note that devfs has been obsoleted by udev,

-	  This option appears if you have CONFIG_DEVFS_FS enabled. Setting
