[PATCH 1/3] scsi: scsi_devinfo: add COMPAQ PD-1 multi-LUN ATAPI device quirk

The Compaq-branded variant of the Panasonic/Matsushita LF-1195C PD/CD
combo drive is a multi-LUN ATAPI device that exposes the CD-ROM on
LUN 0 and a PD optical drive on LUN 1.

An entry already exists for the "MATSHITA PD-1" variant with OEM
firmware.

Add the Compaq-branded variant with the same BLIST_FORCELUN |
BLIST_SINGLELUN flags so that additional LUNs are scanned and commands
are serialised, matching the existing entries.
