fs: jffs2: Move SYS_JFFS2_SORT_FRAGMENTS to Kconfig
Move the symbol SYS_JFFS2_SORT_FRAGMENTS to Kconfig and use the only remaining part of doc/README.JFFS2 that is still relevant and useful to the help for this option. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>

-JFFS2 options and usage.
------------------------
-
-JFFS2 in U-Boot is a read only implementation of the file system in
-Linux with the same name. To use JFFS2 define CONFIG_CMD_JFFS2.
-
-The module adds three new commands.
-fsload - load binary file from a file system image
-fsinfo - print information about file systems
-ls - list files in a directory
-chpart - change active partition
-
-If you do now need the commands, you can enable the filesystem separately
-with CONFIG_FS_JFFS2 and call the jffs2 functions yourself.
-
-If you boot from a partition which is mounted writable, and you
-update your boot environment by replacing single files on that
-partition, you should also define CONFIG_SYS_JFFS2_SORT_FRAGMENTS. Scanning
-the JFFS2 filesystem takes *much* longer with this feature, though.
-Sorting is done while inserting into the fragment list, which is
-more or less a bubble sort. That algorithm is known to be O(n^2),
-thus you should really consider if you can avoid it!
-
----
-
-TODO.
-
- Remove the assumption that JFFS can dereference a pointer
- into the disk. The current code do not work with memory holes
- or hardware with a sliding window (PCMCIA).
