imx7dsabresd: Fix the boot of a NXP kernel

Booting a NXP kernel with mainline U-boot leads to the following
kernel crash:

,----
| caam: probe of 30900000.caam failed with error -11
| Unable to handle kernel NULL pointer dereference at virtual address 00000004
| pgd = 80004000
| [00000004] *pgd=00000000
| Internal error: Oops: 805 [#1] PREEMPT SMP ARM
`----

This happens because NXP kernel expects MX7 to boot in secure mode,
so introduce mx7dsabresd_secure_defconfig that selects CONFIG_MX7_SEC
and allows booting a NXP provided kernel successfully.
