[coreboot] [PATCH] Fix SB600 SATA and add support for port 2-4

[Bao, Zheng]

What you said reminded me to connect more drives when the board boots.
Yes, it changed. If 1st and 2nd ports are both connected, they can both
be correctly detected and initialized. Then I unplugged the drive on 1st
post and didn't change the BIOS, the 2nd ports couldn't be initialized
as it was. I check our asm code and can't find any tip.

Thanks for testing!
This is very strange. It seems the hardware does not follow the BDG. Did
you have 4 drives attached at the same time or was it 1 drive attached
to another port each time?

Could you please write your own implementation of 4-port setup so we can
compare this?
