Remove valueless definition of hard-selected RAMFS option

Since CONFIG_RAMFS is currently hard-selected to "y", and since
Documentation/filesystems/ramfs-rootfs-initramfs.txt reads as follows:

"The amount of code required to implement ramfs is tiny, because all the
work is done by the existing Linux caching infrastructure.  Basically,
you're mounting the disk cache as a filesystem.  Because of this, ramfs is
not an optional component removable via menuconfig, since there would be
negligible space savings."

It seems pointless to leave this as a Kconfig entry.

-          Ramfs is a file system which keeps all files in RAM. It allows
-          read and write access.

-          It is more of an programming example than a useable file system.  If
-          you need a file system which lives in RAM with limit checking use
-          tmpfs.
