Breno Lima c6d5809fe4 mx6dq: hab: Fix chip version in hab.h code 
Since commit 8891410c729b ("MLK-19848 mx6dq: Fix chip version issue for
rev1.3") it's not possible to call the HAB API functions on i.MX6DQ
SoC Rev 1.3:

Authenticate image from DDR location 0x12000000...
undefined instruction
pc : [<412c00dc>]          lr : [<8ff560bc>]

The hab.h code is defining the HAB API base address according to the
old SoC revision number, thus failing when calling the HAB API
authenticate_image() function.

Fix this issue by using mx6dq rev 1.3 instead of mx6dq rev 1.5.
