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

Move a whole bunch of copy-pasta code from soc/intel/{bdw,skl,cnl,icl,
tgl,ehl,jsl,adl} and cpu/intel/{hsw,model_*} to cpu/intel/common.
This change just moves the code. Rework is done in CB:46588.

SA SMRAMC register PCI offset 0x88 is deprecated for ICL, JSL and TGL.
Removing the register programming for these platforms. The write to
this register does not take effect and remains configured to 0, even
when programmed.

This is a copy patch from Tiger Lake SoC code.
The only changes done on top of copy is changing below configs:
1. SOC_INTEL_TIGERLAKE -> SOC_INTEL_TIGERLAKE_COPY
2. SOC_INTEL_JASPERLAKE -> SOC_INTEL_JASPERLAKE_COPY
3. SOC_INTEL_TIGERLAKE_BASE -> SOC_INTEL_TIGERLAKE_BASE_COPY
We started with initial assumption that JSL and TGL can co-exist.
But now we see the SoC code in Tiger Lake is relying on too many
compile-time directives to make two SoCs co-exist. Some of the
differences are listed below:
-> Kconfig: Multiple Kconfig options using
if SOC_INTEL_{TIGERLAKE/JASPERLAKE}
-> GPIO: GPIO communities have their own differences.
This requires conditional checks in gpio.asl, gpio.c, gpio*.h,
pmc.h and gpio.asl
-> PCI IRQs: Set up differently for JSL and TGL
-> PCIe: Number of Root ports differ.
-> eMMC/SD: Only supported on JSL.
-> USB: Number of USB port are different for JSL and TGL.
-> Memory configuration parameters are different for JSL and TGL.
-> FSP parameters for JSL and TGL are different.
The split of JSL and TGL SoC code is planned as below:
1. Copy Tiger Lake SoC code as is, and change SoC Kconfig
to avoid conflicts with current mainboard builds.
2. Clean up TGL code out of copy patch done in step 1.
Make it JSL only code. The SoC config still kept as
SOC_INTEL_JASPERLAKE_COPY.
3. Change JSL SOC Kconfig from SOC_INTEL_JASPERLAKE_COPY to
SOC_INTEL_JASPERLAKE, dedede and jasperlake_rvp boards can
bind to SoC code from soc/intel/jasperlake. This step establishes
Jasper Lake as a separate SoC.
4. Clean up current JSL code from TGL code. This step establishes
Tiger Lake as a separate SoC.
