mtd: remove obsolete JEDEC mapping drivers

JEDEC device support was removed in v2.6.22. (It had been marked as BROKEN (indirectly) since at least v2.6.12.) When it was removed the two JEDEC mapping drivers that depended on it should have been removed too. Do so now.

-
-   The Octagon 5066 is a SBC based on AMD's 586-WB running at 133 MHZ. It
-   comes with a builtin AMD 29F016 flash chip and a socketed EEPROM that
-   is replacable by flash. Both units are mapped through a multiplexer
-   into a 32k memory window at 0xe8000. The control register for the
-   multiplexing unit is located at IO 0x208 with a bit map of
-     0-5 Page Selection in 32k increments
-     6-7 Device selection:
-        00 SSD off
-        01 SSD 0 (Socket)
-        10 SSD 1 (Flash chip)
-        11 undefined
-
-   On each SSD, the first 128k is reserved for use by the bios
-   (actually it IS the bios..) This only matters if you are booting off the
-   flash, you must not put a file system starting there.
-
-   The driver tries to do a detection algorithm to guess what sort of devices
-   are plugged into the sockets.
