Port the ACPI opregion implementation that resides in
drivers/intel/gma to older platforms.
It allows to include a vbt.bin and allows GNU/Linux to load the
opregion as ASLS is being set.
Windows' Intel will likely ignore it as it relies on legacy VBIOS
to be loaded at 0xc0000.
Tested successfully on DG43GT (x4x) with vbt.bin,
with X200 (gm45) with vendor option rom and
D945GCLF (i945) with fake vbt.

This simplifies computing dram timings a lot.
This removes computation of rank size based on columns, rows,
banks,... and uses the information in SPD byte 31. The result of this
is that dimms with multiple asymmetric ranks are not supported
anymore. These however are very rare and most likely never tested on
this platform.
This also uses i2c block read instead of byte read to speed up the
raminit. The result is less time is being spend reading SPDs.
It still keeps smbus read byte as a backup if i2c block read were to
fail.

Inspired by gm45 code, which sets this value the same way.
Some values for tRD on 800 and 1067MHz FSB were set wrong because the
CAS/Freq selection was wrong. CAS was often selected to low and when
fixing CAS this results in tRD being too high, due to an incorrect
lookup table which caused instability.

Vendor BIOS leaves UPMC1 untouched (on 945gc the default is 0x0203).
Not running PCIEx16 init which is valid for 945gm seems to fix all
issues and instabilities related to the PEG port.
According to lspci the link width is at the desired x16.
It is unknown if devices requesting a lower width work automatically
or need more configuration.
What happens is that IGD gets disabled by the disable function in
gma.c when an external GPU is found unless
CONFIG_ONBOARD_VGA_IS_PRIMARY is set.
Setting IGD as secondary makes Linux (4.10) hang, so this behavior is
a requirement for now.

This reuses some of gm45 code to set up the panel.
Panel start and stop delays and pwm frequency can now be set in
devicetree.
Linux does not make the difference between 945gm and gm45
for panel delays, so it is safe to assume the semantics of those
registers are the same.
The core display clock is computed according to "Mobile Intel® 945
Express Chipset Family" Datasheet.
This selects Legacy backlight mode since most targets have some smm
code that rely on this.
This sets the same backlight frequency as vendor bios on Thinkpad X60
and T60.
A default of 180Hz is selected for the PWM frequency if it is not
defined in the devicetree, this might be annoying for displays that
are LED backlit, but is a safe value for CCFL backlit displays.

The selection of the SSC reference frequency for LVDS was based on a
completely unrelated clock.
The `ssc_freq` flag should be set when the SSC reference runs at a
different frequency than the general display reference clock (DREF).
For most platforms, there is no choice, i.e. for i945 and gm45 the SSC
reference always differs from the display reference clock (i945: 66Mhz
SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and
newer, it's the same frequency for SSC/non-SSC (120MHz). The only,
currently supported platform with a choice seems to be Pineview, where
the alternative is 100MHz vs. the default 96MHz.

Some possible problems are:
* on 800MHz fsb CPUs the igd sometimes has artifacts on the screen;
* on 800MHz fsb CPU memtest results vary a lot;
* since a commit 45e11aa0a5 "Add/Combine Broadwell Chromebooks using
variant board scheme" that does not affect this northbridge, the
display shows garbage as soon as Linux (4.8) modesets the display.
A fix is to hardcode the core display and render clocks to their
maximum, potentially also improving graphical performance.
Vendor bios on all boards in coreboot with this northbridge have the
same value in this PCI config address.
