Always start the executive in Exception Level 1, Non-Secure mode. If we boot in EL3 Secure with GICv3 then we have to initialize the distributor and redistributor to set up G1NS interrupts early in the boot sequence before stepping down from EL3S to EL1NS. Now there is no need to distinguish between secure and non-secure world execution after the primary core boots, so get rid of the AARCH64_IS_NONSECURE configuration option.
