These chips are still using LATE_CBMEM which was agreed upon to
be removed after release 4.7. It is now more than 1 year later
and they still linger around.
The work and review to bring this code up to date can happen on
the 4.9 branch and then squashed together and merged back into
mainline when done.

Newer CPUs/SoCs need to configure other features via the
IA32_FEATURE_CONTROL msr, such as SGX, which cannot be done if the
msr is already locked. Create separate functions for setting the
vmx flag and lock bit, and rename existing function to indicate that
the lock bit will be set in addition to vmx flag (per Kconfig).
This will allow Skylake/Kabylake (and others?) to use the common
VMX code without breaking SGX, while ensuring no change in functionality
to existing platforms which current set both together.
Test: build/boot each affected platform, ensure no change in functionality

This patch introduces 3 helper function for cpuid(1) :
1. cpu_get_cpuid() -> to get processor id (from cpuid.eax)
2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx)
3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx)
Above 3 helper functions are targeted to replace majority of cpuid(1)
references.

This also caches the TSEG region and therefore increases MTRR usage
a little in some cases.
Currently SMRR msr's are not set on model_1067x and model_6fx since
this needs the MSRR enable bit and lock set in IA32_FEATURE_CONTROL.
This will be handled properly in the subsequent parallel mp init
patchset.

Initially, I wanted to move only the Kconfig DISPLAY_MTRRS into the
"Debug" menu. It turned out, though, that the code looks rather generic.
No need to hide it in soc/intel/.
To not bloat src/Kconfig up any further, start a new `Kconfig.debug`
hierarchy just for debug options.
If somebody wants to review the code if it's 100% generic, we could
even get rid of HAVE_DISPLAY_MTRRS.

The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow
backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART,
because it's using its interface. The individual UART drivers
select DRIVERS_UART, because they implement the interface and
depend on the common UART code.
Some guards had to be fixed (using CONSOLE_SERIAL now instead of
DRIVERS_UART). Some other guards that were only about compilation
of units were removed. We want to build test as much as possible,
right?

The exception occurs when trying to read `MSR_COUNTER_24_MHz`, located
at 0x637. This MSR only exists on Haswell-ULT CPUs.
So, allow boards to use the TSC monotonic timer instead. They can do
this by placing `select TSC_MONOTONIC_TIMER` in the mainboard Kconfig.

This makes i82801ix use the common smm southbridge code to set up smm
relocation and smi handler setup. This is needed in this change for the
the smm relocation code relies on some southbridge functions provided
in the common code. Some of the old code is kept for the Q35 qemu
target.
This also caches the TSEG region and therefore increases MTRR usage a
little in some cases.
Currently SMRR msr's are not set on model_1067x and model_6fx since this needs
the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled
properly in the subsequent parallel mp init patchset.
Tested on Thinkpad X200: boots and going to and resuming from S3 still
works fine.

If CPU 0's stack grows to large, it will overflow into CPU 1's stack.
If CPU 0 is handling the interrupt then CPU 1 should be in an idle loop.
When the stack overflow occurs it will override the return pointer for
CPU 1, so when CPU 0 unlocks the SMI lock, CPU 1 will attempt to return
to a random address.
This method is not foolproof. If code allocates some stack variables
that overlap with the canary, and if the variables are never set, then
the canary will not be overwritten, but it will have been skipped. We
could mitigate this by adding a larger canary value if we wanted.
I chose to use the stack bottom pointer value as the canary value
because:
* It will change per CPU stack.
* Doesn't require hard coding a value that must be shared between the
.S and .c.
* Passing the expected canary value as a parameter felt like overkill.
We can explore adding other methods of signaling that a stack overflow
had occurred in a follow up. I limited die() to debug only because
otherwise it would be very hard to track down.
TEST=built on grunt with a small and large stack size. Then verified
that one causes a stack overflow and the other does not.
Stack overflow message:

%edx gets clobbered before the c handler is invoked. This is just a

When generating a backtrace we need an indicator when we have hit the
beginning of the stack. The i386 ABI states that %ebp points to the next
stack frame. NULL can be used to indicate the end of the stack.
We could add a NULL return pointer at %ebp+4, but I decided to omit it
since a NULL stack pointer can be used as an indicator that there is no
return pointer.

An unidentified combination of speculative reads and branch
predictions inside WRPROT-cacheable memory can cause invalidation of
cachelines and loss of stack on models based on NetBurst
microarchitecture.
Therefore disable WRPROT region entirely for all family F models.
As an extreme example, just changing the location of a constant string
passed to printk() has been witnessed to make a the boot fail early on
in romstage.

In the end it does not look like RCBA register offsets are fully

This moves CAR stack under variable MTRRs and removes
old CAR code that used complex fixed MTRRs and placed
