Both southbridges need to be done at once since this southbridge code
is used for different northbridges, which fails to compile when done
separately.
This needs an acpi_name functions in the northbridge code to be
defined.
TESTED on Intel DG43GT: show correct PIRQ ACPI entries in
/sys/firmware/acpi/tables/SSDT.

Libgfxinit provides a better alternative to the native C init. While
libgfxinit mandates an ada compiler, we want to encourage use of it
since it is in much better shape and is actually maintained.
This way libgfxinit also gets build-tested by Jenkins.

This change also makes sure that the sum the uma regions (TSEG, GSM,
GSM) is 4MiB aligned. This is needed to avoid cbmem_top floating between
2 usable ram region, since cbmem_top is aligned 4MiB down to easy MTRR
setup for ramstage. At least tianocore requires this and fails to boot
without it.
Better MTRR are achieved by making the memory 'hole' till 4GiB exactly
2Gib.
This code mimics how it is done in nb/intel/gm45 and achieves similar
results.
TSEG is enabled and set to 8M since this makes it easier to reuse the
common smm setup / parallel mp code and makes it possible to cache the
ramstage in there like how it's done on newer targets.
TESTED on Intel DG43GT.

Especially on ICH7 failing to do so results in i2c block read being
unusable. On ICH10 this problem doesn't manifest itself that much.
This moves disabling the watchdog reboot to the northbridge code like
i945 (even though it technically is southbridge stuff).
TESTED on Intel DG41WV: hacking on raminit is much nicer since no
need to do a hard power down for +4s are needed to clear the timeouts.

There have been discussions about removing this since it does not seem
to be used much and only creates troubles for boards without defaults,
not to mention that it was configurable on many boards that do not
even feature uart.
It is still possible to configure the baudrate through the Kconfig
option.

This board uses the reset defaults for DxxIP and DxxIR.
The datasheet "Intel ® I/O Controller Hub 10 (ICH10) Family"
mistakenly says in the D31IP register that all function have INTB as
default. This is however not true as documented in the reset default
value.
This fixes the DSDT such that the SMBus device gets a route for the
INT C interrupt it uses.

This mainboard features is an G43 northbridge, ICH10 southbridge and
Winbond W83627dhg SuperI/O. This board is impossible to flash
internally with vendor bios (BIOS region is WP and other regions like
IFD and ME are read only and inaccessible respectively). Due to either
ICH10 or board layout it is also impossible to do ISP, which requires
desoldering flash chip. To make hacking more easy there is an empty
SPI header next to spi flash pads which can be hooked up to a SPI
flash.
What works:
* 2 DDR2 dimms per channel (tested with 1+2G in CH0 and 2+2G in CH1);
* SATA with AHCI
* Integrated GPU with option rom (extracted from a Gigabyte vendor
bios)
* VGA (on DVI) with NGI if patched to use DVI gmbus port for output
* PCI
* Reboot and S3 resume
* Descriptor mode with ME disable straps and ME region absent (no
working gbe in this configuration though)
* USB.
What does not work:
* GBE (probably requires working ME);
* Analog on DVI port out is shaking, which is not the case with vendor
BIOS (setting clockgen on smbus 0x69 like vendor fixes it).
* Booting with ME enabled (needs raminit patches for that)
Not tested:
* Sound;
* All the rest.
Not coreboot related problems:
* Flashing this board with vendor bios is a PITA and requires
desoldering flash chip;
* In situ programming is not possible.
TESTED with SeaBIOS and Linux 4.10.8
