Coverity detects dereferencing a pointer that might be "NULL" when
calling report_resource_stored. Add sanity check for dev to prevent
NULL pointer dereference.

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'

These two identifiers were always very confusing. We're not filling and
injecting generators. We are filling SSDTs and injecting into the DSDT.
So drop the `_generator` suffix. Hopefully, this also makes ACPI look a
little less scary.

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.

As the SSDT generator for LDNs expects a "parent" PNP device
for proper ACPI code generation, validate that it is present.
Make sure the devicetree looks as expected and print a BUG message
if that's not the case.

No BUG message was printed.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.
