mtd: rawnand: Change Kconfig titles and re-order a bit the list

This list is a mess, while some items should probably not be in the
raw/ sub-directory, others are definitely at the right place but not
with the right description. Write uniform titles and group IPs by
vendor.

NAND controllers will appear under the list named "Raw/parallel NAND
flash controllers" while the other drivers will appear under
"Misc". Software ECC engines will later be moved out of the raw/
directory.

-	  The downside of leaving this option disabled is that if bad blocks
-	  are detected by Linux, they will not be recorded in the BBT, which
-	  could cause future problems.
-	  Once you enable this option, new filesystems (INFTL or others, created
-	  in Linux or other operating systems) will not use the reserved area.
-	  The only reason not to enable this option is to prevent damage to
-	  preexisting filesystems.

+	  and 2000 TSOP/Alon), Linux reserves some space at the end of the
+	  device for the Bad Block Table (BBT).  If you have existing INFTL
+	  data on your device (created by non-Linux tools such as M-Systems'
+	  DOS drivers), your data might overlap the area Linux wants to use for
+	  the BBT.  If this is a concern for you, leave this option disabled and
+	  Linux will not write BBT data into this area.
+	  The downside of leaving this option disabled is that if bad blocks
+	  are detected by Linux, they will not be recorded in the BBT, which
+	  could cause future problems.
+	  Once you enable this option, new filesystems (INFTL or others, created
+	  in Linux or other operating systems) will not use the reserved area.
+	  The only reason not to enable this option is to prevent damage to
+	  preexisting filesystems.
+	  Even if you leave this disabled, you can enable BBT writes at module
+	  load time (assuming you build diskonchip as a module) with the module
+	  parameter "inftl_bbt_write=1".
