Previously the ME PCI interface (HECI) was being reported as present in
the DMAR ACPI table even when ME firmware was missing or the PCI device
was hidden and HECI would be unresponsive.
Now we check via the PCI config space itself to verify if the HECI
is present or not.
Note that this test could fail if ME firmware is present but
HECI is disabled in devicetree, because it would not advertise that the HECI
exists even though there is a running ME. Perhaps this behaviour is desirable
because in this case you won't see the HECI in the lspci tree anyway.

According to "G45: Volume 3: Display Register
Intel 965G Express Chipset Family and Intel
G35 Express Chipset Graphics Controller" some registries
are set incorrectly in gm45/gma.c.
Some values are changed after comparing them with the values
the i915 linux kernel (3.13 was used) module sets while modesetting.
The values were obtained using 'intel_reg' from intel-gpu-tools,
during a normal boot and with 'nomodeset' as a kernel argument.
Some registers that don't exist on gm45 are set in gma.c, which is
probably the result of copying code from a more recent intel
northbridge.
The result is that that gm45 laptops with wxga displays still work as
before. gm45 laptops with wxga+ or higher resolution now just work,
where previously a black screen was shown.
TEST: build with native graphic init and flash on a gm45 target, like
lenovo x200.

On i945 the vram size is the default 8mb. It is also possible
to set it 1mb or 0mb hardcoding the GGC register in early_init.c
The intel documentation on i945, "Mobile Intel 945 Express Chipset
Family datasheet june 2008" only documents those three options.
They are set using 3 bits. The documententation also makes mention
of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it.
The other non documented (straight forward) bit combinations allow
to change the VRAM size to those other states.
What this patch does is:
- add those undocumented registers with their respective vram size to
the i945 NB code;
- make this a cmos option on targets that have this northbridge.
TEST: build, flash to target, set cmos as desired and boot linux.
On Debian it can be found using "dmesg | grep stolen".
NOTE: dmesg message about reserved vram are quite different depending
on linux version

Now hardcode maximum memory frequency capability to 800MHz, as
all chipsets in x4x family support PC2-6400 according to the datasheet.
CAS latency detection also relies on this, and has been cleaned up.
Ram initialization does not work with FSB 1333MHz / DDR2 800MHz combination,
so disable this combination for now, and reduce to 667MHz instead.
Still don't know why this is the case, but FSB1333/667 works.
These changes should now allow existing configurations to continue working,
while providing support for previously unworking configurations, due to
previous buggy CAS latency detection code.
