This is very similar to Sandy/Ivy Bridge, except that there's several
registers to program in GDXCBAR. One of these GDXCBAR registers has a
lock bit that must be set in order for the memory controller to allow
normal access to DRAM. And it took me four months to realize this one
bit was the only reason why native raminit did not work.

This brings the old raminit implementation for CX700 back. It was
removed in commit e99f0390b9 (Remove VIA CX700 northbridge sup-
port). The code is mostly unchanged, three minor issues are fixed:
* A shift (>>= 2) was missing when reading tRRD from SPD byte 28.
The fixed value matches what the vendor BIOS of a VIA EPIA-EX
board programs. The code also suggests that we are looking for
a small value (<= 19 for DDR2-533).
* We allow the board port to specify which clock outputs should
be enabled now. This is necessary for the VIA EPIA-EX, which
needs the ALL_MCLKO setting (instead of the previously hard-
coded MCLKO2.
* When programming the DQS output delays, we considered the 1~2
rank values only for single-rank configurations. Changing the
`< 2` to `<= 2` brings us closer to the vendor values on the
VIA EPIA-EX.
Otherwise a lot of cosmetics changed. Partly because the original
code was to be #included into another C file, but also to satisfy
checkpatch. Also, all the #if'd code was removed (32-bit width
option, ECC, etc.).

This northbridge provides a lot of knobs for fine-grained tuning of the
FSB drivers. The programming manual calls this "Host AGTL+ I/O Driving
Control". We program the known good values for use with a VIA C7 CPU,
and warn about use with different CPUs.
The numbers were pulled out of raminit of the original CX700 port.
Originally, there was a write to 0x83 as well, to set bit 1 which
triggers a soft reset of the CPU. It was amidst a table, so it
seems unclear if it was put there intentionally.

This patch flips the polarity of CONFIG_USE_1G_PAGES_TLB into
CONFIG_NEED_SMALL_2MB_PAGE_TABLES which is off by default, meaning
CPUs added in the future will automatically build the smaller 1GB pages.
We can expect support for this feature to be available on all future CPU
generations (with the possible exception of embedded edge cases), so
this default setting should make mistakes less likely and keep
maintenance effort lower. (Besides, enabling the support where it
doesn't work fails fast, whereas keeping it disabled where it could work
is an inefficiency that can easily go overlooked for a long time.)
While this is technically a CPU feature, not a northbridge feature, we
support a lot more individual CPUs than northbridges in the pre-SoC era,
and they tend to be closely coupled anyway. So select the option at the
northbridge level for older CPUs to keep things simpler.
