Enhance SCSI disk module to produce Disk Info protocol on the same Block IO handle:
SCSI Interface GUID: Physical SCSI disk IDE Interface GUID: ATAPI device run in legacy IDE mode AHCI Interface GUID: ATAPI device run in AHCI mode. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9584 6f19259b-4bc3-4df7-8a09-765794883524
