All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.
In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs
in their Makefiles.

There are manual timeout-loops which use a fixed value and udelay().
In all cases there is a debug printk() inside this loop which, when
enabled, takes way longer than the counted microsecond delay. This
leads to the result that e.g. a 1 second delay takes nearly an eternity
if the debug messages are enabled due to the longer function execution
time.
This patch uses the stopwatch scheme for the timeout-loops which still
makes sure that the timeout period is maintained while it takes longer
function calls like printk() into account. In order to keep the minimum
delay between two register accesses on the TPM keep the udelay(1)-call.
TEST=Enable TPM debug messages on a board where the TPM hits a timeout
by failure and make sure that the debug messages occur in the log
just in the timeout period. It still works as expected if the debug
messages are disabled.

function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm
function is created which then calls do_mp_init_with_smm, prints the
error if it didn't return CB_SUCCESS and passes the return value of
do_mp_init_with_smm to its caller.

printing a message, also add a comment at the mp_init_with_smm call

de-asserted before PCIe link training during S0i3 resume. Otherwise the
concerned gpp_bridge_2 PCIe device is not enumerated on Soi3 resume.
This change feeds in the WWAN_AUX_RST_L GPIO in the DXIO descriptor so
that SMU de-asserts this reset on S0i3 resume.
BUG=b:199780346
TEST=Build and boot to OS in Guybrush. Perform suspend/resume cycles for
500 iterations. Ensure that the PCIe devices enumerate fine.

Instead of a const port descriptor, make it configurable. This will help
to avoid adding duplicate tables for every minor configuration updates.
BUG=None
TEST=Build and boot to OS in Guybrush. Perform suspend/resume, warm and
cold reboot cycles for 10 iterations each.

Using cb_err as return type clarifies the meaning of the different
return values. To not change the return types of mp_run_on_aps which is
exposed outside of this compilation unit to keep the scope of this patch
limited, the return value of run_ap_work gets translated to the int
values in mp_run_on_aps. This could also be done by a cast of the
run_ap_work return value to int, but an explicit translation of the
return values should be clearer about what it does there.
