In some arm64 boards, MMU regions are set so userspace can access all
peripherals (MT_P_RW_U_RW), including the GIC.
This seems like a mistake, which has been copy/pasted in some boards.
Change this to no userspace access by default (MT_P_RW_U_NA),
like the other boards.

This commit introduces driver for granting access for own grant
table and for mapping/unmapping foreign gref. Grant tables are used
for data exchange between Xen domains via shared memory page(s) (e.g.
for sharing ring buffer with driver data) This functionality is
widely used and needed for implementing PV backend/frontend drivers.

<soc.h> has been traditionally been used as a proxy to HAL headers,
register definitions, etc. Nowadays, <soc.h> is anarchy. It serves a
different purpose depending on the SoC. In some cases it includes HALs,
in some others it works as a header sink/proxy (for no good reason), as
a register definition when there's no HAL... To make things worse, it is
being included in code that is, in theory, non-SoC specific.
This patch is part of a series intended to improve the situation by
removing <soc.h> usage when not needed, and by eventually removing it.

Linker files were not migrated with the new <zephyr/...> prefix. Note
that the conversion has been scripted, refer to #45388 for more details.

In order to bring consistency in-tree, migrate all soc code to the
new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

The autoconf.h header is not required because the definitions present in
the file are exposed using the compiler `-imacros` flag.

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.

This commit removes usage of Xen emulated PL011 SBSA UART in favor of
Xen PV console minimal implementation. Now boot log and application
output can be directly taken from hypervisor domain console, instead of
virtual UART.
Also Xen VM doc was updated according to these changes.

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
