ARM: Add arch/arm/cpu/armv7/Kconfig with non-secure and virt options 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_ARMV7_BOOT_SEC_DEFAULT as a proper Kconfig option.

tegra: Boot in non-secure mode by default Upstream Linux is broken with default configs when PSCI, thus non-secure mode is enabled. So the user should explicitly enable this mode, e.g. when she disabled CONFIG_CPU_IDLE in Linux (in which case it's safe to use). We can revert this workaround once Linux got fixed.

Some boards however (like the RPi2) run in HYP mode. There, we need to modify the HYP version of system registers and HYP mode only supports the long descriptor PTE format.
