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.

xenvm: Add support for using GICv3 Currently xenvm board/soc is configured to use GICv2 and there is no clean way(without modifying the source code) to alter this configuration to use GICv3. Due to the increasing number of users wishing to use GICv3, add a new configuration called xenvm_gicv3 that enables GICv3. Create a Kconfig file and add a config XENVM_USE_GIC_V3 that, if set, will cause SOC_XENVM to select GICv3 instead of GICv2. Update documentation accordingly. Take the opportunity to remove the unnecessary config options from the defconfig files. Signed-off-by: Michal Orzel <michal.orzel@arm.com>

soc: arm64: xenvm: move Kconfig option to soc The XEN_INITIAL_DOMAIN option was defined at board level, however, some drivers such as the XEN serial driver has dependencies on XEN_INITIAL_DOMAIN, meaning any new board has to define its own copy of XEN_INITIAL_DOMAIN. Move the option to SoC Kconfig. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>
