[PATCH 06/11] mtd: remove lart flash driver

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The sa1100 lart platform was removed, so its flash driver is
no longer useful.

- * Limitations:
- *
- *    Even though this driver is written for 3 Volt Fast Boot
- *    Block Flash Memory, it is rather specific to LART. With
- *    Minor modifications, notably the without data/address line
- *    mangling and different bus settings, etc. it should be
- *    trivial to adapt to other platforms.
- *
- *    If somebody would sponsor me a different board, I'll
- *    adapt the driver (:
