Make ARM_AARCH64 Port SMP ready

[NikJen26]

This change makes the ARM_AARCH64 Port ready for SMP use.

Description

As part of my master thesis I developed this Port. It was specifically developed for the Zynq Ultrascale Platform but only contains changes that are applicable to all AARCH64 Processors and therefor should work on all of them. I tested all of the code in Release and Debug build using the FullDemo of FreeRTOS. All Tests ran fine for over a week continuously.

Test Steps

Testing the code requires implementing the vPortStartCore function used in port.c in a file called hardware_setup.c . I can only provide a specific version for the Zynq Platform. Please let me know if I should provide them as part of the Community-Supported-Ports repository.

Checklist:
