This patch switches the cbmem utility from its own IP checksum
implementation to the commonlib version (which is good because the old
one had a couple of bugs: doesn't work on odd sizes and may overflow
its carry accumulator with input larger than 64K).

This patch adds a bit of optimized assembly code to the ipchksum()
algorithm for x86 targets in order to take advantage of larger load
sizes and the add-with-carry instruction. The same assembly (with one
minor manual tweak) works for both 32 and 64 bit mode (with most of the
work being done by GCC which automatically inserts `rax` or `eax` in the
inline assembly depending on the build target).

This patch moves the IP checksum algorithm into commonlib to prepare for
it being shared with libpayload. The current implementation is ancient
and pretty hard to read (and does some unnecessary questionable things
like the type-punning stuff which leads to suboptimal code generation),
so this reimplements it from scratch (that also helps with the
licensing).
This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
series for architecture-specific optimization.

The configuration of the PCIe clock generators in the FCH was moved from
the FSP to coreboot, since all registers are documented. This
initialization is however tightly integrated in the rest of the PCIe
init code inside the reference code. In the FSP case, this code was
manually removed. openSIL will do that part of the initialization so
that there's no coreboot-specific change needed in openSIL. This will
also avoid the problems caused by mismatching configurations done by the
coreboot code and the PCIe init part of the reference code.

Commit d252776668 ("tree: Replace And(a,b) with ASL 2.0 syntax")
replaced two instances of `And(var, mask) == 0` with `var & mask == 0`.
This expression needs parentheses - `(var & mask) == 0`.
Without parentheses, it is always false, since the masks are nonzero
(`var & (mask == 0)`; `var & 0`; `0`).
This caused brightness changes on Intel GMA to take longer than
normal since the status was never checked. The brightness would
change immediately, but another brightness change could not occur until
the first change timed out.
This was most noticeable in KDE, which waits for the brightness change
to complete before accepting another brightness up/down keypress.
Tapping brightness up/down repeatedly would take much longer to reach
max/min brightness due to many presses being ignored.
It is noticeable in GNOME as well but less obvious. Tapping brightness
up/down repeatedly would handle all keypresses, but the display's
actual brightness would lag behind and skip some intermediate steps.
I tested both Librem 13v2 and Librem 14, as far as I know this would
apply to all systems configuring brightness with Intel GMA.
Test: Verify brightness keys respond quickly again on Librem 13v2 / 14.
