Commit d6ac8e22c7 ("acpi/x86: define ACPI IO registers for
PVH guests") broke ARM64 build of mk_dsdt.c due to introduction
of XEN_ACPI_CPU_MAP[_LEN] macros that are needed only for x86
guests.
We could fix the build by dealing specifically with those macros
but since post-MADT code is not executed on ARM64 anyway we can
compile it for x86 only.

Define VCPU available map address (used by AML's PRSC method)
and GPE0 CPU hotplug event number. Use these definitions in mk_dsdt
instead hardcoded values.
These definitions will later be used by both the hypervisor and
the toolstack (initially for PVH guests only), thus they are
placed in public headers.

At the moment this flag is unconditionally set for PVHv2 domains. Note that
using this boot flag requires that the FADT table revision is at least 5.

Update the structure of the FADT table to version 5, and use that version for
PVHv2 guests. Note that HVM guests will continue to use FADT 4. In order to do
this, add a new field to acpi_config that contains the ACPI revision to use by
libacpi. Note that currently this only applies to the FADT.

The tools (such as mk_dsdt) can be cross-built when it may not be
desirable to build them on the target.
The commit c4ac1077 "libxl/arm: Generate static ACPI DSDT table"
introduced support of ARM64 in mk_dsdt but also break cross-building
tools because the ACPI tables are not correct.
While mk_dsdt should generate ACPI table for the target architecture, it
currently generates the one for the host. This is because the source
code contains reference to the host architecture (__aarch64__,
__x86_64__, __i386__) when it should be the target architecture.
Replace all __aarch64__, __x86_64__, __i386__ by the corresponding
CONFIG_*.
Also expose the CONFIG_* to the source code as the currently only
exposed to the Makefile.

There is no reason to build, for example, dsdt_pvh.asl for hvmloader. We
pass which DSDTs to build via DSDT_FILES parameter.
If DSDT_FILES is empty all DSDTs for a particular architecture will be built.

Current usage of sed in the libacpi Makefile make uses of non-POSIX options,
that are not available on all the OSes supported by the Xen tools.
The '-i' option has slightly different semantics between GNU and BSD sed
implementations, while on the GNU version the suffix is optional, on the BSD
one it is not. Also BSD sed seems to have problems parsing the script
itself, reporting "extra characters at the end of d command".
Fix those issues by using a temporary intermediate file, and replace the
script with a simpler version that achieves the same purpose (removing the
initial license header comment).

The arm64 build for libacpi was broken due to two reasons:
1. ACPI_BUILD_DIR was appended twice to dsdt_anycpu_arm.c.
2. The inclusion of firmware/Rules.mk overrided XEN_TARGET_ARCH, which
made CONFIG_ARM disappear.
Fix those by:
1. Correctly generate full path for dsdt_anaycpu_arm.c.
2. Include tools/Rules.mk instead, because libacpi/Makefile doesn't rely
on settings in firmware/Rules.mk.
While at it, use CONFIG_ARM_64 instead of CONFIG_ARM as it is more
accurate.

It uses static DSDT table like the way x86 uses. Currently the DSDT
table only contains processor device objects and it generates the
maximal objects which so far is 128.
While the GUEST_MAX_VCPUS is defined under __XEN__ or __XEN_TOOLS__, it
needs to add -D__XEN_TOOLS__ to compile mk_dsdt.c.
Also only check iasl for aarch64 in configure since ACPI on ARM32 is not
supported.

PVH guests require DSDT with only ACPI INFO (Xen-specific) and Processor
objects. We separate ASL's ACPI INFO definition into dsdt_acpi_info.asl so
that it can be included in ASLs for both HVM and PVH2.
