scsi-disk: add SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk for Macintosh
Both MacOS and A/UX make use of vendor-specific MODE SELECT commands with PF=0
to identify SCSI devices:
- MacOS sends a MODE SELECT command with PF=0 for the MODE_PAGE_VENDOR_SPECIFIC
(0x0) mode page containing 2 bytes before initialising a disk
- A/UX (installed on disk) sends a MODE SELECT command with PF=0 during SCSI
bus enumeration, and gets stuck in an infinite loop if it fails
Add a new SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk to allow both
PF=0 MODE SELECT commands and implement a MODE_PAGE_VENDOR_SPECIFIC (0x0)
mode page which is compatible with MacOS.
