Introduce a new Kconfig option CPU_CORTEX_A78 to enable support for the Arm Cortex-A78 CPU architecture within Zephyr. This configuration can be selected by boards or SoCs that utilize the Cortex-A78 core, enabling architecture-specific features and optimizations as needed.

Add CPU bindings for the Cortex-A78 to enable reading CPU device tree properties in Kconfig. This is required to correctly configure and use CPU-specific settings based on the device tree. Signed-off-by: Appana Durga Kedareswara rao <appana.durga.kedareswara.rao@amd.com>
Add initial support for the Versal Net SoC APU, which is based on the Arm Cortex-A78 processor. It includes basic wiring for memory regions, UART, interrupt controller, and timer. The versalnet_apu.dtsi file defines peripherals shared across the SoC, while versalnet_a78.dtsi captures peripherals private to the Cortex-A78 processor. These device trees lay the groundwork for further APU-based development on the Versal Net platform. Signed-off-by: Appana Durga Kedareswara rao <appana.durga.kedareswara.rao@amd.com>

…-A78) Introduce a generic board configuration for the APU on the Versal Net SoC, which is based on the ARM Cortex-A78 processor. This board setup provides a baseline environment for enabling and testing Cortex-A78 features and peripheral integration on the APU subsystem.

Add support for running the APU ELF on QEMU using the `west build -t run_qemu` target. QEMU integration is now wired through west and Twister for the `versalnet_apu` board. Signed-off-by: Appana Durga Kedareswara rao <appana.durga.kedareswara.rao@amd.com>

does the board support SMP or not? it seems you enables four A78 Cores but didn't enable CONFGI_SMP.

Thanks for the review @JiafeiPan Basic SMP functionality only tested that's why didn't enabled it by default, planning to add SMP on top of this once properly tested.
