move FADT data initialization out of fadt_setup() into dedicated
init_fadt_data() that will set common for pc/q35 values in
AcpiFadtData structure and acpi_get_pm_info() will complement
it with pc/q35 specific values initialization.
That will allow to get rid of fadt_setup() and generalize
build_fadt() so it could be easily extended for rev5 and
reused by ARM target.
While at it also move facs/dsdt/xdsdt offsets from build_fadt()
arg list into AcpiFadtData, as they belong to the same dataset.

acpi_get_pm_info only adds reset stuff + version info on top of
previously initialized common data, right?

It's possible but I wanted to keep pc/q35 specific pieces explicitly
split from common data initialization as personally for me this way
it's easier to see difference (i.e. there is no need to jump into init_fadt_data()).
Perhaps I should rename init_fadt_data() to init_common_fadt_data().

I guess it is sort of slipped in from (7/9) patch,
as this fields can be 0 and don't need dynamic patching.
Theoretically facs/dsdt could be 0 for x86 too if we drop support
for 32bit guests (which isn't going to happen).
I can move it to 7/9 which moves build_fadt into generic code from x86 specific,
which is more appropriate place for it.

build_append_foo() API doesn't need explicit endianness
conversions which eliminates a source of errors and
it makes build_fadt() look like declarative definition of
FADT table in ACPI spec, which makes it easy to review.
Also it allows easily extending FADT to support other
revisions which will be used by follow up patches
where build_fadt() will be reused for ARM target.

what about Hypervisor Vendor Identity field (8 byte) in version 6.0?

OK so can't we assert before the (f->rev >= 6) check above?

not supported yet, hence assert below.
When it's added we should update assert to the next supported revision.

there is no point to read fields here but not actually
checking them so drop it and read only header + dsdt/facs
addresses since it's needed later to fetch that tables.
With this cleanup we can get rid of AcpiFadtDescriptorRev3/
ACPI_FADT_COMMON_DEF which have no users left.
