[SCSI] Improve inquiry printing
- Replace scsi_device_types array API with scsi_device_type function API. Gets rid of a lot of common code, as well as being easier to use. - Add the new device types in SPC4 r05a, and rename some of the older ones. - Reformat the printing of inquiry data; now fits on one line and includes PQ. I think I've addressed all the feedback from the previous versions. My current test box prints: scsi 2:0:1:0: Direct access HP 18.2G ATLAS10K3_18_SCA HP05 PQ: 0 ANSI: 2 Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
