From dyoung@ -- bump max TX DMA size to avoid pathological condition with TSO.
Rework agp_i810 attachment code a little.

- Fix up error branches in agp_i810_attach.

- Use a separate bus space handle for the GTT, whether it is in a
separate BAR or a subregion of the MMIO device registers, so that

(a) agp_i810_write_gtt_entry and agp_i810_post_gtt_entry are easier to
follow, and

(b) we can map the GTT prefetchable eventually.
If -v is set and unknown cacheinfo desc is found, print it.
 Move forward read pointer to the next line in the buffer
to prevent corrupting the most old line.
