coreboot: re-add asus kgpe-d16/kcma-d8/kfsn4-dre

Libreboot 20220710 was the last release to support these
boards. I plan to eventually port code differences between
D8/D16 to Dasharo, for KCMA-D8 support in Dasharo, to then
use in Libreboot for both KCMA-D8 and KGPE-D16, but I have
no plans to update the KFSN4-DRE code, at least for now.

Libreboot 20220710 used coreboot 4.11, whereas this patch
makes use of coreboot 4.11_branch; the crossgcc toolchains
no longer compile on modern distros, so I spent time patching
those (tested in Debian Sid, will also work on Arch Linux and
so on).

The acpica downloads now fail, in 4.11_branch, because Intel
made some changes upstream for these tarball downloads. Newer
coreboot works around this by grabbing tarballs from github,
itself a non-ideal solution, but I digress; this patch changes
coreboot crossgcc (in 4.11_branch) to download the acpica
tarball from libreboot rsync, where I've added it.

This patch also re-introduces the PIKE2008 fix, where empty
option ROMs for these are inserted into CBFS. This prevents
SeaBIOS from loading the real option ROMs, which would cause
SeaBIOS to hang. This means that SAS drives are not supported
in SeaBIOS, for these boards in Libreboot.

I previously said, in the Censored Libreboot c20230710
announcement, that I would *only* merge D8/D16 when I've
added Dasharo support to Libreboot, and use that, but the
work to make coreboot 4.11_branch compile is something I'm
quite proud of and I see no reason to exclude from lbmk
master branch.

Honestly, there's not much different than 4.11, code-wise.
I *probably* won't use 4.11_branch for the next Libreboot
release, on D8/D16. By then, I might have Dasharo integrated
in lbmk instead. We shall see.

+Subject: [PATCH 3/6] Tweak cmos defaults for KCMA-D8 (for a little speed
+ boost)
+
+63xx CPUs have the option to use a reduced latency value inside the crossbar.
+Setting "experimental_memory_speed_boost=Enable" aparently only has an effect
+on 63xx CPUs and may, in certain cases, yield a slight memory bandwidth
+increase (according to Timothy Pearson), but maybe it also works for
+43xx CPUs.
+
+Setting "l3_cache_partitioning=Enable" will increase performance in certain
+situations. See:
+https://developer.arm.com/documentation/100453/0401/functional-description/l3-cache/l3-cache-partitioning?lang=en

+This really only benefits 63xx opterons which are less reliable in libreboot due
