Orginally fetch_mac_string_vpd() has been special cased around
a device_index of 0/1 that causes a number of edge cases and

splitting up the functional into logical workers where we can
deal with each edge case in a more bounded way.

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.

PC Engines apu2 had many problems with PCIe cards detection. The cards
were inconsistently detected when booted from G3, S5 or after a reboot.
AGESA can reset PCIe slots using GPIO via callback. Use it to reset the
slots that support using GPIO as reset signal.

The `link_frequency_270_mhz` setting was originally used by the native
graphics init code for Sandy/Ivy Bridge, which is long gone.
The value of this information (which board had it set) is questionable.
The only board that had an LVDS panel and set it to 0 was the ThinkPad
L520, where native graphics init was never reported to work. Also, the
native graphics init only used it for calculations, but never confi-
gured the hardware to use a specific frequency. A look into the docu-
mentation also doesn't reveal any straps that could be used to confi-
gure it.

The PWM-granularity chicken bit in the Wildcat Point and Lynx Point
PCHs has actually the opposite meaning of the one for Sunrise Point
and later. When the bit is set, we get a divider of 16, when it's
unset 128. Flip the bit!

_DCS, _DGS and _DSS are required by specification. However,
we never implemented them properly, and no OS driver com-
plained yet. So we stub them out and keep the traditional
behavior in case an OS driver checks for their existence.
The old implementations also only returned static values as
there never was any write to their GNVS variables. The TRAP()
that was called in one place is actually implemented by some
ThinkPad's SMI handler as docking event. However, as the call
precedes these SMI handlers in coreboot history, it's most
likely an accident.
