The porting of Asus P8Z77-M mainboard required changing certain Super
I/O configuration registers that were ignored in devicetree.cb because
they aren't listed as resources. Add the declaration so they can be
changed.
This change is nowhere near enough as the current structure is
insufficient to allow changing configuration registers in the 0xE?
range, which this board also needs.
TEST=Changes to config regs 0xf4, 0xf5 in LDN 9 are reflected when
inspected using superiotool -d.

Really old versions of W83977TF Super I/O had an IR logical device, but
is no longer the case. It does not exist in the newer W83977EF version,
installed in some Asus P2B family boards, and served by this same code.
Add a config option on the off chance we may see board with it (as if
we would) and don't include this device unless it is set. Saves us from
the need to declare a not-present device off and/or extraneous PNP
device errors about a not-present device.

This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

Sometimes coreboot needs to compile external code (e.g.
vboot_reference) using its own set of system header files.
When these headers don't line up with C Standard Library,
it causes problems.
Create stdio.h and stdarg.h header files. Relocate snprintf
into stdio.h and vsnprintf into stdarg.h from string.h.
Chain include these header files from string.h, since coreboot
doesn't care so much about the legacy POSIX location of these
functions.
Also move va_* definitions from vtxprintf.h into stdarg.h where
they belong (in POSIX). Just use our own definitions regardless
of GCC or LLVM.
Add string.h header to a few C files which should have had it
in the first place.

Replace DSDT ACPI code and DSDT injection with a SSDT only solution.
The current implementation shows some issues on current Linux, which
might be due to external ACPI objects, which are then injected into
DSDT or the fact that those objects only use 3 characters.
Replace all the DSDT code with an SSDT generator.
Tested on HP Z220:
Boots into Linux with no ACPI errors. The SSDT can be disassembled.

The specified PNP registers PNP_MSC0-E (F0-FE) are part of the iLPC2AHB
bridge's index/value interface. They are no one-time config registers
so we can't specify a sane value in the devicetree.
Thus, drop them to stop coreboot from complaining about the missing
entries.
