[MTD] Fixup probing logic for single 16bit devices
The change to the generic probe to look for the
smallest width of chip first is causing some problems
on boards with a single 16bit device.
The problem seems to be the jedec_match() is truncating
the device-id read from the table to match against the
one read from the hardware, causing a match against the
partial id of some chips with 16bit IDs (such as the
SST39LF160)
This fixes things for my own board, but something may
need to be done if the same problem is exhibited for
chips with an 8bit ID

[JFFS2] Use a single config option for write buffer support
This patch replaces the current CONFIG_JFFS2_FS_NAND, CONFIG_JFFS2_FS_NOR_ECC
and CONFIG_JFFS2_FS_DATAFLASH with a single configuration option -
CONFIG_JFFS2_FS_WRITEBUFFER.
The only functional change of this patch is that the slower div/mod

used when CONFIG_JFFS2_FS_WRITEBUFFER is enabled.

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

[JFFS2] Core changes required to support JFFS2-on-Dataflash devices.
DataFlash page-sizes are not a power of two (they're multiples of 528
bytes). There are a few places in JFFS2 code where sector_size is used
as a bitmask. A new macro (SECTOR_ADDR) was defined to calculate these
sector addresses. For non-DataFlash devices, the original (faster)
bitmask operation is still used.
In scan.c, the EMPTY_SCAN_SIZE was a constant of 1024.
Since this could be larger than the sector size of the DataFlash, this
is now basically set to MIN(sector_size, 1024).
Addition of a jffs2_is_writebuffered() macro.
