[JFFS2] Add support for JFFS2-on-Dataflash devices.
For Dataflash, can_mark_obsolete = false and the NAND write buffering
code (wbuf.c) is used.
Since the DataFlash chip will automatically erase pages when writing,
the cleanmarkers are not needed - so cleanmarker_oob = false and
cleanmarker_size = 0
DataFlash page-sizes are not a power of two (they're multiples of 528
bytes). The SECTOR_ADDR macro (added in the previous core patch) is
replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is
selected.
