The kernel booted on DEC3000/300 cannot figure booted SCSI device.

>Fix:

Unknown, but I think this problem caused by dec_3000_300.c
Rev 1.29 change. The kernel says the tcds slot number is 2,
but slot number in bootdev_data from SRM is 4.
I'm not sure why ctrl_dev_type in bootdev_data is FLAMG_IO,
not PMAZ-DS.
