Add more revision support for the new i.MX6DQ tape-out (TO1.5).  This
TO1.5 is the Rev 1.3 as documented in i.MX6DQ data sheet, because TO1.3
and TO1.4 are never revealed.

Changes since v1:
 - Add a note in code for the numbering mismatch between code and
   data sheet
 - Fix a typo of tape-out in commit log
