Jeuk Kim	096434fea1	hw/ufs: Modify lu.c to share codes with SCSI subsystem ... This patch removes the code that ufs-lu was duplicating from scsi-hd and allows them to share code. It makes ufs-lu have a virtual scsi-bus and scsi-hd internally. This allows scsi related commands to be passed thorugh to the scsi-hd. The query request and nop command work the same as the existing logic. Well-known lus do not have a virtual scsi-bus and scsi-hd, and handle the necessary scsi commands by emulating them directly.
