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.

This is mostly written from scratch and uses common spd ddr2 decode
functions.
This improves the following:
* This fixes incorrect CAS/Freq detection on DDR2;
* Fixes tRFC computation; tRFC == 78 is a valid timing which is
excluded and 0 ends up being used; (TESTED)
* Timings selection does not use loops;
* Removes ddr3 spd decode and is re-added in follow-up patches using
common ddr3 spd functions;
* Raminit would bail out if a dimm was unsupported, now in some cases it
just marks the dimm slot as empty;
* It dramatically reduces stack usage since it does not allocate 4
times 256 bytes to store full SPDs, amongs other unused things that
were stored in sysinfo;
* Reports when no dimms are present;
* Uses i2c block read to read SPD which is about 5 times faster than
bytewise read, with a fallback to smbus mode in case of failure,
which does seem to happen when the system is forcefully powered
off.

Simplifies our C interface function gma_gfxinit(), due to the following
changes:
* *libgfxinit* knows about the underlying PCI device now and can
probe MMIO addresses by itself.
* The framebuffer mapping is now completely handled inside the
library where we validate that we neither overflow
- the stolen memory,
- the GTT address space, the GTT itself nor
- the aperture window (i.e. resource2 of the PCI device)
that we use to access the framebuffer.
Other changes:
* Fixes and a quirk for DP training.
* Fix for DP-VGA adapters that report an analog display in EDID.
* Fixes for Skylake support with coreboot.
* DDI Buffer drive-strength configuration for Haswell, Broadwell and
Skylake.
* `gfx_test` can now be run from X windows (with glitches).
* Compatibility with GCC 7 and SPARK GPL 2017.

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.
