Add arch/arm/cpu/armv7/Kconfig with non-secure and virt options, this is a
preparation patch for adding an env variable to choose between secure /
non-secure boot on non-secure boot capable systems, specifically this
prepares for adding CONFIG_CPU_V7_SEC_BY_DEFAULT as a proper Kconfig option.

Changes in v2:
-Drop all the FIXME-s, use proper CPU_V7 and CPU_V7_HAS_foo checks instead
