cosolidated into one file and moved to common code CPU car folder.
- exit_car_fsp.S is from APL, DNV soc folder is clubbed into one file
and moved to common CPU car.
- The new file apollolake/fspcar.c is addded to pass tempraminit
parameters.
- Coffee lake Soc uses FSPT to support Intel Security features like
BootGuard verify boot and Measured boot. Add FSP CAR support for CFL
by programming tempraminit parameters and add FSP_T_XIP default if
FSP_CAR is selected.

Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also
implement board_reset() as a "full reset" (aka. cold reset) as that
is what was used here for hard_reset().
Drop soc_reset_prepare() thereby, as it was only used for APL. Also,
move the global-reset logic.
We leave some comments to remind us that a system_reset() should
be enough, where a full_reset() is called now (to retain current
behaviour) and looks suspicious.
Note, as no global_reset() is implemented for Denverton-NS, we halt
there now instead of issuing a non-global reset. This seems safer;
a non-global reset might result in a reset loop.

With https://github.com/IntelFsp/FSP/pull/4 merged, this allows using
Intel's FSP repo (that we mirror) to build a complete BIOS ifd region
with a simple coreboot build, automatically drawing in headers and
binaries.
This commit covers Apollolake, Coffeelake, Skylake, and Kabylake.
Skylake is using Kabylake's FSP since its own is FSP 1.1 and Kabylake's
also supports Skylake.
Another candidate (given 3rdparty/fsp's content) is Denverton NS, but
it requires changes to coreboot's FSP bindings to become compatible.
Cannonlake, Whiskeylake require an FSP release.

As per the ACPI specification, there are two types of power button
devices:
1. Fixed hardware power button
2. Generic hardware power button
Fixed hardware power button is added by the OSPM if POWER_BUTTON flag
is not set in FADT by the BIOS. This device has its programming model
in PM1x_EVT_BLK. All ACPI compliant OSes are expected to add this
power button device by default if the power button FADT flag is not
set.
On the other hand, generic hardware power button can be used by
platforms if fixed register space cannot be used for the power button
device. In order to support this, power button device object with HID
PNP0C0C is expected to be added to ACPI tables. Additionally,
POWER_BUTTON flag should be set to indicate the presence of control
method for power button.
Chrome EC mainboards implemented the generic hardware power button in
a broken manner i.e. power button object with HID PNP0C0C is added to
ACPI however none of the boards set POWER_BUTTON flag in FADT. This
results in Linux kernel adding both fixed hardware power button as
well as generic hardware power button to the list of devices present
on the system. Though this is mostly harmless, it is logically
incorrect and can confuse any userspace utilities scanning the ACPI
devices.
This change gets rid of the generic hardware power button from APL
and relies completely on the fixed hardware power button.
BUG=b:110913245
TEST=Verified that fixed hardware power button still works as expected
on octopus.

On APL, call to pmc_fixup_power_state was added because GPE0_EN
registers did not have the right bits set on resume from S3 -- this
was a result of GPE_CFG registers getting reset to their default state
on resume. GPE_CFG registers are programmed as part of pmc_gpe_init
which was previously done only in ramstage.
However, with change a673d1c (soc/intel/apollolake: Initialize GPEs in
bootblock), call to pmc_gpe_init was added to bootblock which means
that GPE_CFG registers will have the right state by the time control
reaches romstage where pmc_fill_power_state is called. Thus, call to
pmc_fixup_power_state is totally redundant and in fact leads to
side-effects because of the call to pmc_disable_all_gpe at the end of
pmc_fill_power_state.
