Move prmrr_core_configure before clearing MCEs.
This is required for the following patch in order to update microcode
after PRMRR has been configured, but before MCEs have been cleared.
According to Document 565432 this should be no issue in regards to
SGX activation.

The code for enabling ACPI timer emulation is the same for the SoCs
SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to
common code.
APL differs in not having the delay settings. However, the bits are
marked as "spare" and BWG mentions there are no "reserved bit checks
done". Thus, we can write them unconditionally without any effect.
Note: The ACPI timer emulation can only be used by SoCs with microcode
supporting CTC (Common Timer Copy) / ACPI timer emulation.

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

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

The devicetree is not made for user-choosable options, thus introduce
Kconfig options for both SGX and the corresponding PRMRR size.
The PRMRR size Kconfig has been implemented as a maximum value. At
runtime the final PRMRR size gets selected by checking the supported
values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest
to the chosen one.
When "Maximum" is chosen, the highest possibly value from the MSR gets
used. When a too strict limit is set, coreboot will die, printing an
error message.

Some timeouts given were too small when serial console is enabled due to
its spinlock making code runtime worse with every AP present.
In addition we usually don't know how long specific code runs and how
long ago it was sent to the APs.
Remove the timeout argument from mp_run_on_all_cpus and instead wait up
to 1 second, to prevent possible crashing of secondary APs still
processing the old job.
