On Hyper-Threading enabled platforms the MSR_PRMRR_PHYS_MASK was written
when already locked by the sibling thread. In addition it loads microcode
updates on all threads.
To prevent such race conditions only call the code on one thread, such
that the MSRs are only written once per core and the microcode is only
loaded once for each core.
Also add comments that describe the scope of the MSR that is being
written to and mention the Intel documents used for reference.
Fixes crash in SGX MP init.
Tested on Supermicro X11SSH-TF.

This splits the x11-lga1151-series' documentation into a generic and a
board specific section as a preparation for CB:35427.
Additionally this adds some more information on the x11ssh board.

Most of the X11 boards with socket LGA1151 are basically the same boards
with just some minor differences like different NICs (1 GbE, 10 GbE),
number of NICs / PCIe ports etc.
There are about 20 boards that can be added, if there is a community for
testing.
To be able to add more x11 boards easily like x11ssm (see CB:35427) this
restructures the x11ssh tree to represent a "X11 LGA1151 series". There
were multiple suggestions for the structure like grouping by series
(x10, x11, x...), grouping by chipset or by cpu family.
It turned out that there are some "X11 series" boards that are
completely different. Grouping by chipset or cpu family suffers from the
same problem. This is why finally we agreed on grouping by series and
socket ("X11 LGA1151 series").
The structure uses the common baseboard scheme, while there is no "real"
baseboard we know of. By checking images, comparing logs etc. we came to
the conclusion that Supermicro does have some base layout which is only
modified a bit for the different boards.
X11SSH-TF was moved to the variants/ folder with it's gpio.h. As we
expect the other boards to have mostly the same device tree, there is a
common devicetree that gets overridden by each variant's overridetree.
Besides that some very minor modifications happened (formatting, fixing
comments, ...) but not much.
Documentation is reworked in CB:35547

We generally try to stay away from ascribing attributes to (future)
devs. "Rookie guide" refers to the reader, while "tutorial" refers
to the material.
In the same spirit, move from "lessons" to "parts". It's not school :-)

Add support for the X11SSH-TF which is based on Intel KBL.
Working:
* SeaBIOS payload
* LinuxBoot payload
* IPMI of BMC
* PCIe, SATA, USB and M.2 ports
* RS232 serial
* Native graphics init
Not working:
* TianoCore doesn't work yet as the Aspeed NGI is text mode only.
* Intel SGX, due to random crashes in soc/intel/common
For more details have a look at the documentation.
Please apply those patches as well for good user experience:

The issue in question was resolved with commit 334be3289d
("nb/intel/haswell: Add support for PEG").
Also add a link to the known issues for Haswell, which has some
information on PCIe.

This board runs well with coreboot. The documentation part of this
commit lists what works and what doesn't.
Tested with GRUB 2.02 as a payload, loading SeaBIOS 1.12.0 which then
boots FreeBSD 11.2. It has also been tested with GRUB directly booting
Debian GNU/Linux 9.6 (kernel 4.9).
