Extended K8T890 driver to include the K8T800 and K8M800 northbridges

The K8T800 is almost identical to the K8T800Pro, also added to this patch.
The K8T800_OLD is also defined, which is an older version of the K8T800,
but which has no driver and early HT code yet. Also extended the K8M890 VGA
driver to work for the K8M800 (not tested). According to the datasheet, the
K8T890 and K8T800 are similar enough to be able to use the same
initialization code. At least for the K8T800, this is sufficient to have
a working HT link with the CPU, and to initialise the V-Link to the
southbridge.
