[PATCH v2 5/5] scsi: scsi_devinfo: add COMPAQ PD-1 multi-LUN ATAPI device quirk

[Phil Pemberton <philpem@philpem.me.uk>]

The COMPAQ PD-1 (OEM Panasonic/Matsushita LF-1195C) is a PD/CD combo
drive that exposes two ATAPI LUNs: LUN 0 is a CD-ROM (TYPE_ROM),
LUN 1 is a 650 MB PD (TYPE_DISK).

Add it to the SCSI device list with:
  - BLIST_FORCELUN: tells the SCSI layer to scan past LUN 0
  - BLIST_SINGLELUN: serialises commands across the two LUNs, since
    the drive has a single transport and cannot handle concurrent
    operations on both

The INQUIRY strings as reported by the device are:
  Vendor:  "COMPAQ  " (T10 format, space-padded)
  Product: "PD-1"
