[PATCH 20/37] mx6dq: hab: Fix chip version in hab.h code

[Peng Fan (OSS)]

From: Breno Lima <breno.lima at nxp.com>

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>]
reloc pc : [<c8b6d0dc>]    lr : [<178030bc>]
sp : 8ef444a8  ip : 126e8068     fp : 8ff59aa8
r10: 8ffd51e4  r9 : 8ef50eb0     r8 : 006e8000
r7 : 00000000  r6 : 126ea01f     r5 : 0000002b  r4 : 126e8000

resetting ...

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.
