nb/i945/early_init.c: Add FSB800 and 1067 to Egress Port Virtual Channel
Values based on vendor bios and suggested by Arthur Heymans for FSB1067.
FSB1067:
The ratio 1067/800 is proportional to the ratio of EPBAR32(0x2c) bits:
0x1a / 0x14 ~ 1067/800
EPVC1IST:
The ratio is also proportional to FSB ratios: 0x9c / 0xf0 ~ 533/800.
