Various cdb masks incorrectly assumed the GROUP NUMBER field
was 5 bits long. It is actually 6 bits long. Correct.

Please mention all changes in the patch description. I think the READ(16) and
WRITE(16) changes not only change the GROUP NUMBER field from 5 to 6 bits but
also declare the DLD0 bit as supported. Anyway:
