ENGR00287268 mx6: fix the secure boot issue on the new tapout chip
commit 424cb1a79e9f5ae4ede9350dfb5e10dc9680e90b

newer i.MX6 silicon revisions have an updated ROM and HAB API table.
Please see also:

i.MX Applications Processors Documentation
Engineering Bulletins
EB803, i.MX 6Dual/6Quad Applications Processor Silicon Revsion 1.2 to 1.3 Comparison

With this change the secure boot status is correctly displayed
