SRU JUSTIFICATION:

IMPACT:  Western Digital Caviar SE SATA 2nd Generation Hard Drive is not 
recognized by the kernel.

FIX: Make ata_dev_classify() report ATA_DEV_SEMB on the
     sig and let ata_dev_read_id() work around it by trying IDENTIFY once.

TEST: Originator of the bug has tested the kernel in 
http://people.ubuntu.com/~manjo/lp257790-jaunty/ and reported it works.

The following changes since commit 
a63b7d7beeaa1f8f33369cab6419831fa8991e40:

for encrypted symlink targets
