Introduce mach-axiado to support Axiado SoC-based boards. This adds the platform Kconfig and build infrastructure, along with initial SCM3005 board support using the AX3005 SoC.
Introduces AXIADO_AX3005, which selects ARM64, driver model, GIC-v3, and Zynq UART. TARGET_SCM3005 selects ARCH_AXIADO, allowing future SoC variants to share the platform configuration. Secondary cores use spin-table boot. ft_board_setup() corrects the cpu-release-addr in the FDT, which arch_fixup_fdt() overwrites with the post-relocation address. Add U-Boot board support for the Axiado AX3005 based targets, a quad-core ARM Cortex-A53 (ARMv8) platform.
