[PATCH] USB Storage: add alauda support

This patch adds another usb-storage subdriver, which supports two fairly
old dual-XD/SmartMedia reader-writers (USB1.1 devices).

This driver was written by Daniel Drake <dsd@gentoo.org> -- he notes
that he wrote this driver without specs, however a vendor-supplied GPL
driver for the previous generation of products ("sma03") did prove to be
quite useful, as did the sddr09 driver which also has to deal with
low-level physical block layout on SmartMedia.

The original patch has been reformed by me, as it clashed with the
libusual patches.

We really need to consolidate some of this common SmartMedia code, and
get together with the MTD guys to share it with them as well.
