fs: Kconfig: Add a separate option for FS_JFFS2

Browse source 
Rather than using CMD_JFFS2 for both the filesystem and its command, we
should have a separate option for each. This allows us to enable JFFS2
support without the command, if desired, which reduces U-Boot's size
slightly.

If you do now need the commands, you can enable the filesystem separately
with CONFIG_FS_JFFS2 and call the jffs2 functions yourself.

This provides support for reading images from JFFS2 (Journalling
Flash File System version 2). JFFS2 is a log-structured file system
for use with flash memory devices. It supports raw NAND devices,
hard links and compression.
