usb-storage: make sddr09 a separate module

Browse Source 
This patch (as1207) converts usb-storage's sddr09 subdriver into a
separate module.

An unexpected complication arises because of DPCM devices, in which
one LUN uses the sddr09 transport and one uses the standard CB
transport.  Since these devices can be used even when
USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h
require special treatment.  If SDDR09 isn't configured then the
entries remain in unusual_devs.h; if it is then the entries are
present in unusual_sddr09.h instead.

Say Y here to include additional code to support the Sandisk SDDR-09
SmartMedia reader in the USB Mass Storage driver.
Also works for the Microtech Zio! CompactFlash/SmartMedia reader.
If this driver is compiled as a module, it will be named ums-sddr09.
