Xen-related Kconfig options were highly dependand on BOARD/SOC xenvm.
It is not correct because Xen support may be used on any board and SoC.
So, Kconfig structure was refactored, now CONFIG_XEN is located in
arch/ directory (same as in Linux kernel) and can be selected for
any Cortex-A arm64 setup (no other platforms are currently supported).
Also remove confusion in Domain 0 naming: Domain-0, initial domain,
Dom0, privileged domain etc. Now all options related to Xen Domain 0
will be controlled by CONFIG_XEN_DOM0.

Some configurations have the system timer driver hardwired in.
Let's make them compatible with CONFIG_SYS_CLOCK_EXISTS=n.

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.

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.

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
