[U-Boot] [PATCH 2/2] mx7dsabresd: Fix the boot of a NXP kernel

[Fabio Estevam]

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.
