[SCSI] osd_uld: OSD scsi ULD

Add a Linux driver module that registers as a SCSI ULD and probes
for OSD type SCSI devices.

When an OSD-type SCSI device is found a character device is created
in the form of /dev/osdX - where X goes from 0 up to hard coded 64.
The Major character device number used is 260.
