scsi-disk: support setting CD-ROM block size via device options
SunOS expects CD-ROM devices to have a block size of 512, and will
fail to mount or install using QEMU's default block size of 2048.
When initializing the SCSI device, allow the `physical_block_size'
block device option to override the default block size.
