The goal of this commit is to add the GCC/ARMClang non-MPU
port variant for ARM Cortex-R82 processor which is
ARMv8-R AArch64 based.
The work done is inspired by the GCC ARM_AARCH64 FreeRTOS port.
This port has the following features:
* Uses single security state (non TrustZone).
* Supports SMP (Symmetric multi-processing).
* Doesn't support Hypervisor (EL2).
* Doesn't support neither PMSA (MPU) nor VMSA (MMU).
