MLK-19848 mx6dq: Fix chip version issue for rev1.3 

According to iMX6DQ RM, the minor field (low 8 bits) in DIGPROG is not
aligned on silicon revision 1.3. So update get_cpu_rev to correct the
revision.

0x00630002 Silicon revision 1.2
0x00630005 Silicon revision 1.3
0x00630006 Silicon revision 1.6
