warp7: defconfig: Fix CAAM on boot with tip-of-tree
Booting the following image with tip-of-tree we get a CAAM DECO error (and
subsequent crash due to a kernel bug in 4.1).

Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
Fix: Enable the CAAM correctly by setting CONFIG_ARMV7_BOOT_SEC_DEFAULT=y
in the upstream defconfig.
