[PATCH v10 15/15] scsi: scsi_devinfo: add COMPAQ PD-1 multi-LUN ATAPI device quirk

[Phil Pemberton]

The COMPAQ PD-1 and Panasonic LF-1195C combine a CD-ROM on LUN 0 with
a phase-change rewritable (PD) drive on LUN 1.

Add a COMPAQ PD-1 quirk with BLIST_FORCELUN to enable multi-LUN scanning
and BLIST_SINGLELUN to serialize commands across LUNs. Set BLIST_NO_LUN_1F
to skip unpopulated LUNs, which report PQ=0/PDT=0x1f.
