The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
on some targets hits a working mode at lower refresh rate, which is why
display is working on some targets.
The divisors must be such "refclk * (5 * (m1 + 2) + (m2 + 2))/ (n + 2)
/ (p1 * p2)" is as close as possible to the target frequency (which
is defined by the resolution and refresh rate).
This patch also fixes the reference frequency.
This patch reuses linux (4.1) code from drivers/gpu/drm/i915/intel_display.c
to correctly compute divisors.
The result is that some previously not working displays, like many
displays found on the Lenovo T60 might work now.
Some examples of T60 displays that were known to not work (in payload):
Samsung LTN141XA-L01 (14.1" 1024x768)
LG-Philips LP150X09 (15.1" 1024x768)
IDtech N150U3-L01 (15.1" 1600x1200)
IDtech IAQX10N (15.1" 2048x1536)
Samsung LTN154X3-L0A (15.4" 1280x800)
LG-Philips LP150E06-A5K4 (15.1" 1400x1050)
Tested on T60 with 1024x786.

This generates a fake VBT for the Intel i945 graphic device. i945
supports both the mobile chipset 945gm (calistoga) and the desktop
chipset 945gc (lakeport), which is why a VBT with a different id string
needs to be created for each target.
The VBT id string is obtained from the vbios blob in the following way:
"strings vbios.bin | grep VBT".

The intel x4x and gm45 have very similar integrated graphic devices.
Currently the x4x native graphic init enables VGA, while gm45 can output
on LVDS.
This patch reuses the x4x graphic initialisation code
to enable output on VGA in gm45 in a way that the behavior is similar to vbios:
If no VGA display is connected the internal LVDS screen is used.
If an external screen is detected on the VGA port it will be used instead.

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.
