This adds another x11 series board, the X11SSM-F, which is similiar to
X11SSH-TF but differs in PCIe interfaces/devices, GPIO settings and
Ethernet interfaces.

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.
