[U-Boot] [PATCH 1/2] mx7: Place MX7_SEC option in Kconfig

[Fabio Estevam]

MX7_SEC is an existing configuration option that allows booting the
kernel in secure mode.

Place this option in Kconfig, so that boards can select this option
in their defconfig files.

Selecting this option is necessary when booting a kernel provided by
NXP, such as 3.14_GA and 4.1.15_GA.
