arm: aarch64: add Xen virtual machine support This commit adds minimal support for running zephyr as Xen guest. It does not use xen PV console, which is somewhat hard to implement, as it depends on xenbus infrastructure. Instead SBSA-compatible PL011 uart is used.

arm/arm64: Make ARM64 a standalone architecture Split ARM and ARM64 architectures. Details: - CONFIG_ARM64 is decoupled from CONFIG_ARM (not a subset anymore) - Arch and include AArch64 files are in a dedicated directory (arch/arm64 and include/arch/arm64) - AArch64 boards and SoC are moved to soc/arm64 and boards/arm64 - AArch64-specific DTS files are moved to dts/arm64 - The A72 support for the bcm_vk/viper board is moved in the boards/bcm_vk/viper directory Signed-off-by: Carlo Caione <ccaione@baylibre.com>

timer {
dts: Rename compatible arm,arm-timer to arm,armv8-timer The compatible for the ARMv8 timer should have been arm,armv8-timer and not arm,arm-timer. The dts binding file name was correct, just the compatible was wrong. Rename dts, binding, and associated code to use arm,armv8-timer. Fixes #31946 Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
