The min86 example SoC code along with the example mainboard
should serve as a minimal example how a buildable x86 SoC code
base can look like.
This can serve, for instance, as a basis to add new SoCs to
coreboot. Starting with a buildable commit should help with
the review of the actual code, and also avoid any regressions
when common coreboot code changes.
As the example code itself is build-tested, it should advance
with coreboot and can't rot like documentation might. It also
serves as a check what APIs need to be implemented with the
default Kconfig settings.

Check ISST (Intel SpeedShift) availability via CPUID.06H:EAX[7], instead
of relying on the devicetree option `speed_shift_enable`, that is going
to be dropped.

The code configuring ISST (Intel SpeedShift Technology) sets the ISST
capability bits in CPUID.06H:EAX. It does *not* activate HWP (Hardware
P-States), which shall be done by the OS only.
Since the capability is enabled by default (opt-out), there is nothing
to do for us in the enabled-case. Practically speaking, there is no
value at all in disabling the capability, since one can configure the
OS to not enable HWP if that is desired.
The two other bits for EPP and HWP interrupt that were set by the code
are not set anymore, too. It was tested, on three platforms so far
(CML-U, KBL-H, SKL-U), that these are set as well by default in the
MSRs reset value (0x1cc0).
To reduce complexity and duplicated code without actual benefit, this
code gets dropped. The remaining dt option will be dropped in CB:46462.
Test: Linux on Supermicro X11SSM-F detects and enables HWP:
[ 0.415017] intel_pstate: HWP enabled
